Question about Amana PTH123B25AJ Heat Pump Air Conditioner
Amana Heat Pump is 3 ton works okay except emergency heat will not come on...is blowing cold air.
On the heating element [behind the coil, (the springy thing)], at the top end of the element, there is a little thermistor I think it is called. You will have to remove the fan shroud. With the power off, check for continuity if you have a multimeter. If that is the problem (no continuity), you can pick one up at al local heating supply. Just have it soldered back in and reconnect. If the thermistor 's continuity is okay, remove the main board under the control knobs. I have seen these boards burn in the back where the relays are soldered on. If you're really good with a solder you can try to re-solder it. If not, it's about as cheap to buy a new unit as it is to buy the board. Good luck.

The problem sounds like 1 or 2 things either you have a bad sequencer for the heat strip or the emergency heat portion was not wired up.
