These valves do get stuck. They energize for cool and in the dead postion they heat. Your valve is stuck or not energized. Can you here it click or try to energize. If you dont hee the click you do not have voltage to the valve. The valve is powered thru the defrost board. So that might be your problem. If you have voltmeter. Take the two wires off the valve and turnit on cool you should get 24 volts. If you have 24 volts the valve is bad. If you do have voltage to the valve tap the valve while energized and sometimes this will loosen them up. If the board or valve is bad you will have to call a service tech. Russ There is only so much you can do.

Amana Wall unit blows cold air before heating


the unit works by chilling air and the byproduct is heat in the compressor, this is used for heating in the winter and then reversed in summer to blow cold air. It has to blow cold and warm up before it can blow heat.

Our older model amana wall unit is in the garage and worked fine until we programmed a new remote control garage door opener in there this morning. The ac unit was not on at the time but we went to turn it...


If it says E0 then what this usually means is that the unit was unplugged or power was cut to the unit while the unit was on. It then needs to be programmed again. If its the amana/goodman RSKP0009, you need to hold temp up and down arrows down together for two seconds then press off twice. It will take you into the programming mode. Settings are different for heat pump and electric heat models. If you just need a quick fix to get it to cool, I think you can get away with pushing the heat button a few times and then off. If you did it right the display should go off and the light by the off button will turn on. Press cool and it should work.

Heat pump is not kicking in, no heat at 42 degree outdoor temp


HI,

Most likely has a freon leak , or a control problem causing heat to turn on, or if you have a heatpump the reversing valve has a problem.

Blows cool air


This is normal. To maximize the units efficiency the fan continues to run until all the heat from the coil is pasted to the circulating air.

Not heating


Yes, the reversing valve has a separate coil. some energize on cool mode, some on heat mode. Has the thermostat been replaced? I find this a common mistake.
