Having problems with your Air Conditioners ?
Heated air coming out when unit is in Cool Mode
Heat pumps are sometime constructed to "Fail in the heat mode." It could be either the t'stat or the reversing valve. Be sure the t'stat is wired correctly. Usually the"O" terminal is for the reversing valve on the outdoor unit.

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

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.

Thermostat setting I just bought a new house and I have a heat pump-we live in North Carolina. The name on the thermostat is Braeburn and it is a multi-stage 2 heat/ l cool digital thermostat. We have it set at 68 and when the blower first comes on it blows warm air-however then it switches to cool air. And sometimes cool air comes out first. We have set both stages to 68 and it is in the heat mode. Should the 1st and 2nd setting be different?
What i would do is see if the outside unit is working at all. when you first turn it on the air was warm due to the fact that the temperature inside was cooler than the set point. when it get within 2 degrees ... Weather King 12AJA6001AH Air Conditioner

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.

After a cooling cycle, when the thermostat call for more cooling, it take up to 5 minutes after the air handler starts for the compressor motor to restart. The top fan operates on the outside unit, but since the house is not circulating cold air, only the room tep air the house heats up about 3 degrees before the compressor comes back on and cool air begins to come from the ducts. Yes. I know there is a safety feature to protect the compressor, but can the cycle be shortened?
No, this cycle cannot be shortened due to the simple fact that this feature is in place to protect your system. Even if it could be, I wouldn't recommend it.Mat ... Coleman Air Conditioners

We installed a Honeywell RTH230B thermostat on a Trane XE60 Air Handeler this winter. When we put the system on heat it works fine. However, when we put the system on auto for cool the compressor fan comes on but not the air handeler fan. On the air handeler the terminal strip from left to right is R W Y G B/C. The red wire on the R terminal comes from the contactor on the compressor unit. The other wire from the compressor unit is connected to a gray wire that goes to the thermostat. The W

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

My air conditioner stops cooling. Occasionally, it will just function on fan mode even though I confirm that it is on cool mode. Warm air comes out even on the absolute coldest setting. I have to turn it off and use the manual reset button on the plug to get it to work properly. The problem started after the unit iced up one night and it hasn't worked right since. Is there any way to fix this or am I gonna have to get a new AC?
If after reset the A/C cools then the fault seems related to the thermostat or the cut off pressure switch or load cut off.\012However is there is no cooling at all the compressor and the gas pressure- check for leak if gas is absent.- must be ... LG ZW6500R Air Conditioner
We live in southwest Florida. Our HVAC system consists of a air conditioning system with heating coils when it is cool. Yesterday morning we tried the heat nothing come on. Later in the day I tried the air nothing. I tried turning in just the fan nothing. I just checked the breaker I have power where the wires are connected. I went out to the outside unit and pulled the cover. Pushed in a spring loaded plastic switch the fan on outside unit works and shut off when I released the switch. But noth
Hello. Sounds like you do have power. That spring loaded plastic switch is a 24v contactor. It pulls in when energized. If you push it in manually everything shoud run normal. Ck your 24v transformer. On one side (feed) you should have 115v or 220v ... 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

I have a comfortmaker unit with heat strips. The blower fan comes in and blows cool air. I have checked voltage at the transformer, and it is producing 24 vac. The contactor for the fan and condenser never pull in so I replaced the defrost control circuit board. Still only blows cool air and the defrost cycle never comes on. I jump 24vac to the coil on contactor and the defrost fan came on and the condenser came on so the fan motor and start/run capacitor are good. Any suggestions.

Hello, When I set my AC unit to "Heat" and turn it on, the air will come out warm, then after a few hours the air starts to come out cool. To make it warm again I need to set the thermostat to Off position for a few minutes then turn it back to On position then the air comes out warm again. Any idea what could be going on here? thank you!
It sounds like you have a heat pump. When you first turn on the system the heat strips will come on and produce warm heat (referred to as supplemental heat strips), as temperatures rise the heat strips will turn off and the "A" coil will just exchang ... Air Conditioners
