Unless we set the thermostat very high, like 80 degrees, the heater will blow cold air. When the heat does blow, it will eventually stop blowing heat and the fan will continue to blow cold air.


Check and make sure the filter is clean. This sounds like a restriction in the system. If the unit has central cooling make sure ther indoor evaporator coil is clean at the furance.The unit may be cycling the burners on and off at the high heat limit , fan/limit control. You can also eliminate the thermostst from the furance. Turn power off at the furnace and disconnect the wiring from the thermostat. Jumper the red and white wire together. Turn the furnace back on. The furance should run in the heating mode. Try this and see if the problem is still there.

Is it normal operation for these units to EVER blow out cold air or "nonheated" air when unit is in heat mode?


Yes. Heat pumps have to go into defrost just like a freezer when the temp gets too cold outside. The heat pump will temper the indoor air electric heat.

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.

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.

Dead Board on Amana PTC153A50AD


Before the replacement of board please check the fallowing:

- Check for loose terminals and re tight.
- Check compressor terminal post if terminal clips are tight.
- Check compressor resistance and terminal to ground resistance. And check your compressor is not stuck up.
- Check indoor and outdoor blower motor if not stuck up by rotating it with your finger, if it rotates freely then its ok.
- Check the resistance of both indoor and outdoor fan motor resistance and line to ground.
- Check your voltage supply if normal.
- Check the compressor and blower motor capacitor if good.
- Check the unit supply wire if not discolored.
- Check the terminal of your circuit breaker if tight.
If all of the above are ok then it is safe to replace your unit with new board
May be poor contact of the said relay may cause the blowing of your board. Volatage fluctuations is also the suspect or damage solder of the board due to heat.

20 year old central a/c heater not working


Check your thermostat and mode selector setting, thermostat setting should be set at warmer and mode selector setting should be at low heat or hight this is applicable for manual unit.
If it is a remote control just set the remote to heat mode.
