I hope this helps you out. Thanks J, Hi Justin! If the unit is not low on charge then you probably have a stopped up metering device. Our Carrier parts program shows that this furnace has a blower motor part number: HC37TQ113 which is only a 1/5 horsepower motor. It’s blowing fine, just louder than it was last year. It is obvious as you say that the thermostat is losing power. Note: It is cold outside. You should be getting 24 to 28 volts between R and C on the thermostat. A loose connection can cause high amp draw and blow a fuse on the board. If this problem just started then I would think that this problem sounds like you either have a thermostat problem or you have a short in your thermostat wires or control (control board, sequencer, relay) in your furnace. Thanks Steve. I Googled the topic “R26 fuse” and got no-where. Who is the inventor of the modern air conditioner? Weak run capacitors can cause motors to run hot and stop running when they go off on thermal over-load. I would suggest checking the voltage drop to make sure you are getting at least 110 volts out of your generator or home AC electric service when the AC compressor tries to start up. Thoughts? I have a Rheem RBHP-24J18S air handler that has me pulling my hair out. If you have a part that needs replacing it should be under warranty since the unit is only a year old. With this small of a motor I would not think that you could have more than a 2 ton air conditioner installed with this furnace. Test. The liquid inside the compressor can cause the valves inside the compressor to become bent and not sell anymore. (Possibly overheating? Hi! The AC is rather new. – Sam, Hi Sam! Steve. I looked at the thermostat (red wire) and verified I only have <4 volts coming to it. Sorry to hear that you are having this problem with fitting the air handler into your attic. I hope you can easily find out what the problem is. The maintenance people may have wanted you to run the AC all the time (blower all the time) if you have a low refrigerant problem or a low air flow problem to keep the in door evaporator coil from freezing up. I just need to be pointed in the right direction. I check 220 coming in and coming out ok, I check 24 V from left to right of contactor ok. I took the face of the thermostat off the wall and the unit turned off. Do take this quiz and see what you know about heating and air-conditioning Thanks for asking this question. Please let me know what you advise as I desire to get my AC back on soon. Could I go ahead and use the gas valve without the flex hose or should I scrounge the internet for my original gas valve? What could be the problem? Another idea would be to only replace the evaporator coil and not the entire air handler. The most common cause most of the time is because the system is low on refrigerant charge. I’ve never seen this done. Your problem sounds like you have an air conditioner that is either over-charged or you have a restriction in the refrigeration system that is causing it to go off on high head pressure. Compressor getting tight. Hi Jaron! How can I run the fan at max speed while circulating hot water? If the fan blade is free to turn then I would suggest that you have the capacitor tested to make sure it is in good shape. Thanks for asking this question. When the tank is full the HVAC tech should take the reclaimed refrigerant tank to a refrigerant reclaiming facility where they reclaim and process the refrigerant to be used again. And I had just left in prior comment today a request for refrigeration type questions. Hello. This could also be a bad contactor if the contactor coil is getting 24 volts and not closing. I just replaced it again with the second one. I am sorry, but I have never heard of an R26 250 volt fuse. Yes, from your description it does sound like a transformer issue or a loose wire on the primary or secondary side of the transformer. This sounds like the fan is cutting off during the cooling cycle which causes the unit to run high head pressure. I have a propane fireplace and it hadn’t been used for a few years . Compressors that are worn can become tight and hard to start. Troubleshooting type questions would also be appreciated. Not enough refrigerant in the system. Thank you so very much for your military service and kind words! Sorry to hear that you are having so much trouble with your heat pump after the siding installation. Or do you know of any other options? Unit is a Goodman with AC / HP. I would also suggest that you check for a loose fuse if the furnace is equipped with a fuse. I hope you have a nice day! This customer had installed a new 3 wire pilot burner, then decided to clean the old 3 wire pilot burner to see if he could get it working. they said they’ve done it many times to coils and have disassembled many air handlers to get them in the attic. Thanks again! A light brown wire connects to the lead labeled “XFMR” (near the black, blue and red wires and leads)… the other white wire coming from the transformer connects to a neutral lead. I have checked when this happens and the outside condenser is never running, only the air handler from 1-4 minutes (longer the hotter it gets). Find a local hvac school. It wasn’t very old and had few hours of usage . I went back to checking things and found the defrost control switch was failed open so I changed it along with the watt restrictor switch. Could the fan cage just be dirty? Test yourself to see how much you know about the indispensable air conditioner. Between red and black would be 220 to 245 volts and between red to white and black to white would be 120 volts. If you are getting 24 volts between G and C and the blower motor is not coming on then I would test the low voltage going into the fan relay. Steve. Hi Mr. Longmire! Hvac 3rd visit different tech.The loud rattle noise was noticable tech determined it was the gas line. I replace and I notice it was doing the same running even with the thermostat off the unit was running and stopping and making a buzzing noise and burning the contactor and turn in off and on by itself. I would suggest that you check to make sure the thermostat is sending 24 to 28 volts AC to the G (green) thermostat wire when the thermostat is calling for cooling. Please make sure that your filter, blower wheel and evaporator coil are clean. If you do not then you either have a broken wire or a thermostat problem. I have had customers call me thinking their unit is on fire! The airflow is weak/restricted, hot in bedrooms and fine in some area. I would suggest looking for a low voltage fuse on the circuit board. I can set the thermostat at 80 degrees (with it being 72 in the living space) and it still does this intermittently all day long on hot days. I was told to tap something lightly with a hammer in the furnace, but that didn’t do anything. Comment. I bought two. I had a capacitor replaced for each of my Air Conditioning units. I am sorry, I do not know what the problem with your heat pump is. The difference is that the EXPXXUNV0020 filter comes with one EXPXXFIL0020 filter and two reusable black plastic end panels or sometimes called “End Caps”. Hi Lily! Great Question! The blower won’t come on even if I turn it from auto to on. Usually variable speed motors have dip switches that you can set for different amounts of air flow. Copeland makes many of the scroll compressors like your unit has in it. Yes, you are correct, in order to get the cool refrigerant gas coming back to the compressor from and evaporator on the 2nd floor, they might of had to over-charge the unit thus making the compressor have a hard time starting. I feel that scroll compressors are about the best you can get. If the voltage cuts out when the gas goes off then this is the thermostat cutting the gas off. I am sorry that I do not know the answer to your questions. Steve. This customer was kind enough to share with me how he repaired his Bryant Carrier 3 Wire pilot burner. This is a manufacturer’s warning and quite honestly not many people abide or pay attention to it. Just wanted to follow-up…figured out the problem described in my email…the following may help with future customers who buy this board. Hi Richard! I first noticed the problem on a hot day when it kicked on after a 15 minute rest from the last cycle. Best of luck in finding and fixing this problem. I’ve checked the breakers, the float valve, and everything seems fine. Hi Mr. Thibodeaux! My lights are starting to dim more this year and last vs. when I put in my Bryant unit about 5 years ago. If the AC is too small for the furnace blower then the installers might have had to over-charge the unit in order to get cool gas going back to the compressor to keep the compressor running cool. I would like to suggest that you turn the power off to the unit and use a mirror and flashlight to inspect the blower wheel to make sure it is clean. This can cause the compressor to run high head pressure, over-heat and turn off and on while you are away on thermal over-load. True or False: The development of effective temperature control, refrigeration has revolutionized … Sorry you are having problems! I hope the tech can easily find and fix the problem with your furnace. Steve. If you aren’t getting 24 volts between G and C then you might have a thermostat problem. If you tie all these wires together and nothing works then sounds like an electrical problem (maybe thermostat wires) or yes, it could be the control board. You should be able to attach the thermostat wires together R, G and Y. A faulty fan relay on the control board can also cause fans not to run. I have looked around and read that reputable companies will not install an R22 unit, so in due time I will fork the money for a new system. Sorry to hear that your home was hit by lighting! Could it be the blower, fan, wheel, bearing etc. If the compressor is hot on the top then you might be low on refrigerant charge. I would like to suggest that you turn off the power to your furnace and air conditioner and check all wires to make sure they are good and tight and not burnt. Sorry to disappoint you. Steve. These brackets help hold the heat exchanger in place and it they become loose they can rattle and make lots of noise. Then this last time I was checking the furnace. This insures you get the right sized equipment installed. Fan off; Burner on; Fan on; Burner off; Pilot on; Fan off; etc. Learn. The havc tech installed a new sensor worked fine for 1 day then the unit started to vibrate followed by a loud rattle sound. I would make sure they at least replace your compressor with a compatible scroll compressor. I would start with the float switch, the door switch on the furnace blower door, the air handler or furnace control board testing between R and C (should have 24 to 28 volts AC). Was ready to buy a new gas valve but decided to give the whole log set a good cleaning so out it came . My question is “Does what they said make sense?” –tim, Hi Tim! A weak capacitor will also cause a fan motor to stop. I hope someone will see your question and advise. I am afraid to leave it running and do any damage. Hello. It should not run with Y disconnected. On many furnaces the transformer is connected directly to the C (com) and R terminals on the control board. I keep my windows closed all the time now and I don’t really like living in the dark. You could also try disconnecting the Y wire from the thermostat and see if the unit outside stills runs. I hope you have a blessed Memorial Day Weekend! After some research I noticed the most common problems were sequencers, control board, and thermostats. I would suggest that you call or contact Honeywell customer support to see if they can help you out.
