Question about Heating & Cooling

1 Answer

If you unplug an Amana PTAC unit and it freezes what could happen?

I am having massive amounts of freezing and polluted air coming through every part (including the front grill) of my Amana PTAC heater/air conditioner. I had it unplugged and suspect it may have frozen since the Freeze Protection would have not been able to kick in and maybe then cracked. I really need some help with this - we are currently having some very bad pollution and it is really cold and we are just miserable. I do not run the unit, because that makes it worse.

If you are not going to run the unit put a large bag over the out door section. The unit will be just fine.

SOURCE: 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.

SOURCE: ptac fan keeps blowing

Try setting the fan control to "AUTO" this will cause it to cut out with the compressor.

Turn off unit supply and check the blower wheel inside the indoor unit by rotating it manually by your finger if the blower wheel rotates freely then there is something wrong with your fan motor or fan motor capacitor. But if the blower wheel is not rotating freely try to check the fan motor for lubrication or some bushing dried of and no oil

You need to replace your control board, but if you are can repair it by your self you can change the relay that supply the fan and condenser.

SOURCE: It's spitting ice crystals when turned on, and is very noisy.

I'm in a similar situation with a physical neccessity for a/c, year round, even though I live in temperate New Jersey. My husband is an A/C / Refrigeration tech & here's some things you can try to fix your Haier A/C.
1.) Make sure you keep the area where the filter is clean, if you aren't using a filter, you are clogging the air flow much quicker, which can lead to freeze ups.
2.) Due to how shoddy things are made now-a-days & with the storm coming through, you may have a conked out compressor or may have a small refrigeration leak, which can also cause freeze ups.
3.) Make darned sure that the unit is level, if you find it is not, leave your unit off for at least 24 hours for the refrigeration gas & oil in the system to level off.
Sadly, I do not know the model or type of Haier A/C you have & as I'd mentioned, things are no longer made to last like they once were & to get 3 years from a newer model is likely to be the best you can hope for. Haier is fairly decent with wanting to keep up customer morale & if it's a newer unit (younger than 18 months), they may help you to repair it for free or low cost. Good luck with that!

The first 3 answers were from idiots. If a person had read her problem they would understand that it is not a oven / stove, but a PTAC unit that heats and cools a room. This type of unit is what is commonly seen in hotels and motels where the individual heating / cooling system is in each room.

Hisense reset


The outside vent must be OPEN to allow the appliance to get the needed air. In the heating mode of a heat pump, the outdoor coil becomes the condenser. Open the outside vent!

My amana ptac is not heating....the code "np" is displayed....how 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.

Have Ptac units that work fine one minute and 2 hours later just blow warm air.. some that also freeze up the front coils


I think your PTAC is under charge, if the air filter is clean and the evaporator is also clean together with the blower. Check the freon charge and refill if suction pressure is below 50psi and discharge is below 190 psi.
