I understand there is a hidden reset switch in the Amana Heating and Air Condition unit PTH153A50AD. MFG # P1242315R. Could you explain where it is and possibly a diagram? Thanks!

Ok sounds like your transformer is not working. Now as long as no one has removed the doors to the furnace cabinet and they are in place just like the are suppose to be, because there is a door switch that turns off the power to the whole unit until the door is in place correctly. Find the circuit board and look to see it you have a fuse on the board it will look like a car fuse the spade type they are 5 amp fuses. If it is good find the transformer and replace it. If you feel comfortable around electricity there are two sides to the transformer line voltage which is 120 and the secondary side which is 24 volts. If you have a volt ohm meter ohm out the transformer each side line side and low voltage side. An open on either side will be noticed and then replace the transformer. I know this is alot of things to check but just elimanating everything it could be before condemming the transformer. Turn the main breaker off and replace.

Sounds as though the power cord reset switch might be bad and need to be replaced. If not, then there is a short somewhere in the system. Do an ohms test on the switch to determine if it is bad.

SOURCE: My old Amana air conditioner will not turn on. Is

I need to know more. when you call for cooling does the indoor fan run? Does the contactor at the outdoor unit pull in? Have you looked at the fuses,breaker. If it has been very hot lately open the outdoor unit and look for a thing that looks like a large battery it should have 3 to 5 wires on it this is the run/start cap the high outdoor temp will sometimes make this fail. You can see a failed cap 85% of the time just by looking it will have a defromed top or be leaking oil. YOU DON'T WANT THIS OIL ON YOU!

Turn the thermostat as low as it will go and have someone stand out side, they should here the condensor fan and compressor come on at the same time. They are two distinctive sounds so you should
be able to tell if the compressor is running.

If nothing happens and you are skilled with electrical
you can turn power off and remove the electrical
cover to the outside unit. Restore power and carefully
push in the contactor, if the fan and compressor
starts you have a thermostat or low voltage problem.

If just the outdoor fan runs on any attempt, more than likely you need a new capacitor.

My amana ptac is not heating....the code "np" is do I correct this...we just installed the unit and know little about operation. Thanks

I don't see this error code in the manual. I do see nP as an error code for Window Switch lockout. I just had this happen to me and they had me reset the control board.

Remove case, flick master switch to OFF for 10 seconds. Press Heat/Cool same time turn switch back on HOLD until off light comes on.

You should be fixed. Just had to do this for my unit. I was playing around with the settings and turned on the window switch option by accident.

I'm seeing a master switch on the control board, try a reset there. But, sounds like a bad element. You need to test continuity through your heater components. When testing a component unhook wires first, as they will still have continuity even if bad with wires attached.

Can't get unit to turn on. Replaced fuses and still doesn't work - does it work in conjunction with the amana heater that was installed at the same time?

Hi, if you are talking about a split system with a condenser outdoors and a indoor unit, then yes they do work together. When you say you replaced the fuses, are they the fuses at the box that you should have by the outdoor condenser? You should have a electrical box there with 2- cartridge type fuses inside, may be hidden behind plastic cover. When you turn on the thermostat, does the indoor unit blow air but just warm air? If so, the problem may be the thermostat, but more then likely, its in the outdoor unit. Try and locate the breaker for the a/c unit to see if it tripped. If so, reset it and see if it works. If this is not the problem, go to the Amana heater and remove a panel to locate the circuit board. There should be a 3 to 5 amp plug in fuse, looks like a automotive type fuse. See if it has blown. If your not sure, replace it.Make sure you get the panel back on correctly. Check all of these places I have asked you and let me know what is going on. Make sure the thermostat is set for cooling and the temperature is lowered. Please don't forget to rate me on this as I know you will be kind. Please get back to me if you are still having this problem, and explain in more detail what is going on, if its just the outdoor unit and so on.

Amana PTAC PTC093A35AA won't blow heat

The reset button is located behing a panel on the front of the unit that is labeled Heat Reset. If that label is gone then look around, it is a small hole, small enough for a paper clip to fit through.
That being said, I have 137 of these units in one of my hotels and have not had a single one needing to be reset. You probably are going to need a new control board kit. These can be purchased from Amana. They are $130. Make sure that you have pulled the heater coil out and inspected it first. Also, there was a recall years ago where Amana was supposed to contact and send out new voltage switches. These are the round black things that the Brown heater wires connect to on the upper and lower side of the heating coil. You should also try to replace those if you find the coil in good condition. I have had those resolve heating issues. Most of the heating issues were a result of a bad relay on the control board though.
Please remember to rate this fix.
