Having problems with your 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

I know this is late but I had to add a solution to this problem since I had the exact same problem and was able to solve it. The probelm is not your control board. On these units, the heat pump compressor will not kick in unless the temperature you set on the control panel is within 2-1/4 degrees (or 4 degrees depending on your unit model. Otherwise, the unit locks out the compressor until the electric heat coil bring the indoor temperature up to that level - and then will switch the compressor back on for heat pump operation. So the problem is not the control panel or the compressor, it the electric heat coil. The coil has two manual limit switches on it that may be tripped and should be checked. The coil can be easily accessed by shutting down the power, removing 4 screws around the air outlet, pushing the screen up and sliding the panel out the top. The power wires can remain in place while the limit switches are reset. Hope it works.
I had a problem with the heat not coming on in really cold weather. After much reserch and trial and error I a came to the conclusion that the heating coil was not coming on. The cool will reverse on the first stage, heating coil will come on in the second stage.
\012Take the front cover off of the unit. Unscrew the screws on the wire mesh and the two screws on the front below them. Pull out the wire mesh and put it aside. Slowly lift the heatng coil assembly striaght up. Grab the area you just took the screws out of. Once you get the coil out you will see the wires are conected to some terminals. On top of one of the terminals it the MANUAL RESET. It does not say it but it has a button on top. Mine was the one on the far left. Push it in till it clicks. Reassemble the unit in reverse. Mine works fine now.

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.

My 8 yr old Amana heat pump, model RHE48A2D with Honeywell progammable thermostat in heat mode has the blower running constantly. When there is a 6 to 8 degree differnce between room temp and thermostat setting compressor runs as it should, the closer it gets to thermostat setting, it will run about 30 seconds, blower continues to run until getting just cool air, about 5 minutes, compressor kicks back on for 30 sec., continues to do this, thermostat shows it has reached set temperature,

I have an American Standard Heat pump. The unit is one piece is is outside. The problem that I have is that sometimes when the unit kicks on cool, the fan motor will not start. The compressor will run, but quickly freezes up. I can put unit in off and wait for thaw and then put back in cool mode and fan will start. Any ideas?

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 AC starts fine. But the compressor will over heat and shut down in higher temperatures (high 80's lower 90's. It has run without issue on some days like yesterday with temps in the mid 80's. The capcitor was changed but has not fixed the problem. If I let it cool down for an hour, it will restart and continue cooling the house until it overheats again. Amps are in the acceptable range.

I have a split system sanyo heat pump model # kmh0922. The evap. fan will not come on when called for in fan mode. When i put it to heat the indoor fan will also not come on. The compressor runs but the reversing valve seems to stay in the cooling mode. When it is put into cooling the indoor fan goes off after 15 seconds and will not come back on.

Amana ptc094b35am. Whoever knows this I will consider a GENIUS or definitely connected somehow ;-) There is a series of keystrokes on the membrane control panel that will allow the fan to run continuosly when the unit is on (not only when compressor or heater is on) There is no manual switch for this. It must be programmed in the CPU via a menu accessible with a sequence of keystrokes. The only keys are "on,off,heat,cool,temp up/down" I used to have the manual but i lost it. I don't expect much

Hi, I have a 1.5 carrier mini split heat pump. I cant find the model number but believe it was made 2000-2003. This has the remote with the infra red eye mounted in the front of the main unit (like a tv). (There is no other controller as I have seen with other units). The unit is heating and cooling fine, however, it does not seem to be sensing the thermostat. Whether it be in heat or cold, it will turn on and run for about 10 minutes and then shut off and not come again. To get it to run again,
