Hey there, there re a couple of reasons that an ac unit freezes up. The first thing you need to do is defrost it. Then, check to make sure your filter is clean, the side of the coil the air hits first is clean and the scoop on your fan wheel are clean. Next, start it up wait about two minutes then feel the larger line that is covered in black insulation. Normally it is about 55 degrees. If it is colder, you have an airflow problem (dirty fan, coil, filter) if it is warm, you are probably low on refrigerant. If the line is warm, see what temp the small pipe is. If it is cool, you have a restriction in refrigerant flow somewhere. If it is warm to hot, again pointing to low on charge. Let me know what you find out or if you need anything else. Oh yeah, if you are low on refrigerant, make sure the leak is found and repaired or the problem will keep coming back

How to tell if your unit is a heat pump or just air conditioner with electric heat strip


PTH is a heat pump. PTC is an air conditioner only. I don't believe Amana makes electric heat strip-only models based on what I see in their literature. You can just do a google search and look for yourself.

Where is the reset button on an Amana ASZ14 unit?


I don't think the Amana ASZ14 Heat Pump has a reset switch, but you can still reset it by resetting the power (when it's not running... turn your thermostat OFF first).

To reset the power, locate your circuit breaker box. There should be a double-breaker for the Heat Pump and another double-breaker for the Air Handler. Turn them both off for at least 2-3 minutes. Then flip them back on and turn your thermostat back ON.

You're thermostat may also have a RESET button that you can push. I have to reset mine every time I change the batteries in it.

I was wondering the same thing about our unit until I found the specs online and read that it has freeze protection. When the temp goes below 40 degrees, the fan comes on to prevent damage to the unit.

Heater not blowing hot air display says lo


when the coils freeze up , from intake of outside air, when using the heat pump mode, the unit will try to defrost the coils before going back to heat mode. mine did this alot. does it kick back to heat after a few mins? also after 2 years , mine started having issues with the exhaust blower control and would go into warp mode and bang noise.seems like common issues for this unit.whether the amana, or haier version.
