This is a heating and cooling through the wall heat pump. It works normally when heating is selected - the heat pump runs and both speeds of the fan blow warm air. But nothing runs when cooling is selected. In other words the unit works normally when "High Heat" or "Low Heat" is selected but nothing runs when "High Cool", "Low Cool" or "Fan Only" is selected. The position of the Fan Cycle Switch has no effect - behavior of the unit is the same in both positions of the Fan Cycle Switch.

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.

I have an LG mini split ac / heat pump system ( LAN096 ) that is only 4 months old was working great in all ways until suddenly it quit heating. I am sure it happened quickly because I was nearby when very warm air changed to cool ( unheated ) and hasn't heated since. When I shut it down and restart it the indoor fan runs right away, which is not normal and the outdoor unit will run for a minute or so then shut down and stay off. The indoor fan will continue to spin as though it is set in a 'fan

I have a Rheem heat pump/air handler; it draws 2.9amps with only the fan running, 13amps when the heat pump is running and 38amps with the heat strips on. My question is why the unit draws that many amps when in heat pump mode? Isn't all of the work being done by the compressor outside?

I have a 2 year old Duo Therm 15,000 btu Heat Pump AC unit in my RV. The compresser will not come on or even try, in either cool or heat mode, the fans runs in either auto or on position.

My indoor unit on my heat pump will not shut off. The electric heat keeps running, and the fan keeps running. It only happens when it is really cold, like 25deg or below, above that and it functions fine. The outdoor unit shuts off, but the indoor stays running. I do HVAC work, but I have never seen a problem like this. I have switched the stat out, and its just so strange. I figured the relay may be stuck, but if I turn the stat off, it turns off shortly after which tells me it may not be the c

I have a Toyo Aircon split unit Airconditioner/heat pump. 12000 Btu. When in the heating mode, I get the code E8 after it runs for 5 to 15 minutes. At that point it seems to run (at least the internal fan), but the heating aspect seems to be marginal (about the or just above room temp), keeping the room several degrees cooler than what is set. I have been unable to find any source for support of these units. The warranty phone number says it is not connected. Thanks Ed

I have a rheem electric furnace with 2 speed fan, seems like the fan runs full bore when its on, even when i just cycle the blower control to ''on'' and its supposed to run at reduced speed. I have to experience with central heating and air, was wondering if it would be the circuit card with the dip switches. Unit was installed in 2003 with a heat pump.
If it is a variable speed blower most likely the dip switch settings. Check the installation manual to see how to slow it down. ... Air Conditioners

I have an Interthem / Nordyne heat pump model E2EB-015HA. On the outside unit the fan does not turn on when the unit comes on. If I spin the fan it will come on and will run well.

I have a Coleman 5T 13 Seer Heat Pump. When the unit is running there is a lot of vibration (outside unit) and I hear a tinny sound (possibly like the fan hitting something). This seems to be worse during the hottest part of the day. When the unit had its last service they said it was low on freon and recharged it and it seems to be since then that the problem has occurred. Is it possible that the unit is overcharged? And if so is this dangerous, i.e. could it cause permanent damage or immi

Air Conditioning I have a ruud system with the air conditioner outside and the air handler upstairs in the attic. My systems appears to be running, and I can feel cold air at the vents, but I can barely feel it. Like there is no flow. The fan outside is running and the unit in the attic is running. I have no clue what the problem is. The large coil coming from the heat pump outside is cold and has condensation on it. It also seems to have a little ice. It has been extremely hot here in Ge

I have a Rheem A/C Heat Pump split with gas backup. The gas unit is mounted in the air flow directly before the A/C HP coil. Should the gas unit be wired as stage two heat, or is it OK to wire it as just aux/EM heat? There is no other heating unit. What is the difference between stage two and aux? Please note that the aux gas heat cannot come on if the heat pump is running or it may hurt the heat pump due to the gas heat units location.
Stage 2 is okay as long as there is a fossil-fuel kit accessory wired in the field control wiring. EM heat would only allow gas furnace operation if the thermostat is set for EMER HT mode.......this is not ideal and not recommended. Dual-Fuel applic ... Air Conditioners
