It sounds like your PTAC (packaged terminal air conditioner) unit is malfunctioning. When the thermostat is set to heating mode, the PTAC should be blowing warm air, not cold air. There are a few possible causes for this issue:
The PTAC may be low on refrigerant. If the unit is low on refrigerant, it may not be able to properly heat the air.
The PTAC's reversing valve may be stuck in the cooling position. The reversing valve is responsible for switching the flow of refrigerant between heating and cooling mode. If it is stuck in the cooling position, the PTAC will blow cold air even when the thermostat is set to heating mode.
The PTAC's heating element may be malfunctioning. If the heating element is not functioning properly, the PTAC will not be able to heat the air.
I recommend contacting a trained HVAC technician to diagnose and fix the issue with your PTAC. They will be able to determine the cause of the problem and repair it properly.
If you are saying this happens on a really cold night, the assumption is that on milder nights, it seems to work adequately.....If that's the case, there is a possibility that it is marginally sized in capacity to heat the space in which it is installed. If it has a "fresh air" damper setting, make sure that is closed completely, because that is air directly from outside the structure that is being brought in through the blower and adds more load to the space and makes the discharge air feel colder.
EBay often has the control boards for Amana heat pumps, and installing them is fairly straightforward, provided you have some experience with electronics, a soldering iron, etc. Amanapartsonline.com may also be able to sell you the part, which should run between $50 and $150.
Given, however, that the thermostat is also showing problems, as well as what parts are going for these days, I'd seriously consider upgrading to a new unit and selling the old one on Craigslist to offset the cost a bit. If you can find an HVAC technician, someone who's learning HVAC, someone who just wants it for a guestroom where it need not work perfectly or a landlord who can afford to have a secondhand unit fixed and put it in one of their properties for their tenants to buy your fixable old one for a few hundred dollars and a new one only runs about $700, your upgrade will cost less than having the 7-year-old unit repaired, plus you'll be recycling.
Without knowing the model, I would first check the fan motor for seizing, then if not seized, I would replace the fan capacitor. (Available at most appliance parts stores or HVAC parts stores). If this is a motel type PTAC unit (through the wall) I would be looking at the control panel as the third item to check, as these fail often. The fan capacitor is a small cylinder with usually 2 wires coming to it and at least one of them come from the fan and has its values stamped on the side. Hope this helps.
Does this unit have 2 breakers to it? The model you put down is a PTAC and generally just plugs in to the wall so it would have only 1 breaker. If I recall correctly it's got a 5 year warranty on parts so it may be worth it to check with your local HVAC tech and have them do a diagnostic for you. A good place to start would be Amana who can tell you the authorized service company in your area. They'll get the part for free and should roll the diag fee into the repair cost so you'll only pay for labor (if it even needs a part). Their sales and service number is: 1-800-647-2982. Here's a link to your warranty info: http://www.amana-ptac.com/Home/Warranty/tabid/449/Default.aspx
your local hvac outfit should give you pricing tell them you just want the part if your installing it, if you are an hvac company united refrigeration or possibly grainger will have pricing they only sell to contracters as far as i know hope this helps
