20 Most Recent Amana PTH123B25AJ Heat Pump Air Conditioner Questions & Answers

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.

These unit need to tilt backwards so water can drain

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.

provo te lidhesh direkt me spine 220 kompresorin

either fan wheel loose on shaft or bad bearings in motor

you would have to install line tap valves.

bad switch or motor.

use distilled water. clean system with bleach and water

Hi,
If you reset the GFCI button and then when you go to turn it on the button pops again, then you have a short inside the units probably in the fan motor or the compressor..

heatman101

subcooling is only a factor in the cooling mode. you convert the discharge psi to temperture and measure liquid line tempsrture. subtract difference it should be between 8 to 12 degrees.

no its related to the outside condenser

That's correct. If the piston opening is too large it will allow more frozen through than designed and flood the evaporator coil.

the wall stat maybe bad. or wires to remote stat may be shorted

You mean you are using the Emergency heat setting instead of the heat pump????...You're using Natural gas only now tn emergency heat????That's fine...I wouldn't replace a heat pump if you have Natural gas....it's too expensive compared to Gas....you may be able to still use the heat pump as an Air Conditioner only , it depends on what's wrong with it...otherwise you will have to get a Central Air unit instead...cheaper and just use the Gas for heat

br means brown out protection engaged. Power was lost or voltage is to low, check for incoming power at correct voltage

Outside temp too low, so outside thermostat and it's settings will not allow the heat pump to work. But insist on the ausilary heat to work instead. Heat pumps usually do not produce enough heat when below 40F outside temp. If you have Gas heat, it may be more economical than the heat pump below 40F. If electric auxilarry heat, it may compete at 32F. Talk to your dealer, installer, or manufacture.

could be a relay or a board isue

A bit more info would help - like "nothing as in switched off" or "nothing as in motors all running but nothing gets hot".

If you mean that it all sounds and looks as though it is working but there is no heat, then it is possible your changeover valve is jammed. There is usually a four way valve which effectively decides which way your a/c is going to be pumping.

Other reasons are that on this model, it checks to make sure there is at least a 5C difference before it will try and work.

For more help, please be a bit more descriptive as to what it IS doing as well as what it is not - eg: fans / compressor on? strange noises, hissing / error messages and also indoor / outdoor temps
