No Heat Unit works fine in cooling, auto and dehumidification modes but when you select the heating option, the defrost light turns on with no air coming through. Have cleaned the dust filter and outside unit is free of any blockages. Trouble shooting guide in instruction manual does not address this problem. Any help would be appreciated.
In heating mode, the outdoor unit should run to build up pressure and hence heat. To facilitate this, the indoor unit fanmotor will only come on once a sufficient pressure is reached. If you are a bit low on refrigerant, this may not happen. Or it co ... Air Conditioners

When in heat mode heater keeps turning on and off has trouble to keep running cuts in and out for about one minute then only runs for short time and of sometimes trips the switch in meter box ( small green light on unit turns on not the on light the one on the other side)
The cutting in and out is indicating that it has reached its internal thermal limits .. its too hot inside .. that trips a thermal breaker .. the breaker resets when the unit cools ... the problem is almost always caused by not enough air flow ... th ...

Friedrich YM18 230 volt heat pump. The unit has heated and cooled well for about 5 years. Just started heating mode recently and the unit no longer heats. Fan runs OK. Was able to get the heat strip to run for a few minutes (smelled the dust accumulated over the summer burning off). Now, no heating whatsoever. When in the "Money Saver" mode, nothing happens. Fan will not come on and unit will not heat. With "Money Saver" mode off, the fan runs.

My outdoor heat will not operate. It is a Carrier 38YRA042330, with a Carrier Thermidistat thermostat and a Carrier Air Handler 40FFKB005300. I have an H5 error code on the thermostat will I put it in Heat mode and raise the setting to call for heating. I changed the air filter on the air handler when I realized the heat pump was not operating. The air filter was pretty dirty. The system will operate in aux/emerg heat mode, with the fan in Auto or On mode, and will maintain the thermostat
You need to go oside and look for a red reset button on the unit. you tripped the high ressure switch when you let your filter get that dirty. go check on this and when your done if it still is not working then ask me more. ... Carrier Air Conditioners

Amana PTAC Unit is not producing heat. Fan works fine. can not locate manual reset for heat although a label on the unit says there is one. I have an Amana pth153b35ae ptac unit that the heat will not come on. The compressor will run in the cooling mode but not in heat mode. I verified the switching valve is working and the capacitor seems to be fine as the compressor will run in cooling mode. The thermostats seem to be functional because relays can be heard clearly when changing temperature se

Amana #PTC153b50AJ ser 0410686783 Customer heard a pop in unit and it went off. Breaker was tripped. Reset breaker and unit runs in a/c mode but does not heat in heat mode.

We turned power off to the unit to reset fault etc and still no heat. The flashing light just blinks once every 4-5 sec. Could use some help in diagnosis Thanks DK

Amana PTH153B35AK This unit is less than 30 days old, heats fine cools fine, but when i have it in heat mode,set @ 70 or so, as soon as the room heats up, the unit will cycle into a/c mode and blow super cold air for about 5 minutes than return to heating. Sometimes it will reach the desired temp. and turn off like it is supposed to do, but for the most part it just cycles back and forth from hot to cold...Amana has the worse help/service i have ever seen, i was on the phone for an hour,everybod

My bryant heat pump installed in 2008 makes a loud squealing / moaning sound during heat mode,it is a 3 ton,i keep it 66 degrees tring to save money my bill was still 196.00,it goes in to emergency heat mode on its own,this uses the most power,what causes the load noise,during operation,not when it starts,but during the heating prosess,the old one did not do this it was a cumberland brand,do not know maker,
Sounds like a normal defrost cycle. Watch it next time it does it. The outside fan stops, there will be a 'swishing sound'. That is the reversing valve changing over. Then you may see some water vapor rising up fromt he condenser, the emergency hea ... Air Conditioners

Hi, I have a wall mount midea split a/c model- MSG-36HR that will only heat. when put in cool mode it only blow's room temp air and the outdoor unit won't run. On heat mode it works normally. I have cycled power a couple of times, changed modes on the remote numerous times and just in case, changed the batteries in the remote. The unit is about 3 yrs old. Do you have any pointers. Cheers Tom
Most heat pumps are 'fail-safe to heat'. That is: the normal position of the valve which reverses the function is in the position which provides heat. The reversing valve must be powered to switch to the cooling position.Although the ... Midea Air Conditioners

I have a Ruud Heat Pump system. The outside unit makes a humming sound in either heat or cooling modes. The fan won't come on. In cooling mode, the compressor starts up, but them shuts off after about a minute.
Sounds like your condencer fan motor is stuck. Can you take a long rod and when the power is off to the outside unit, spin the fan blade? Maybe it will be enough to get it working again. ... Air Conditioners
