I have an Amana ptac hotel type thru the wall unit. The unit won't turn on - it's plugged in. The gfi button is popped out. There is power to the wall plug. Any ideas?

Question edited for clarity and toss in some CAPS.

You can get wired or wireless.

Check the GFI plug where it plugs into the wall and reset it. Also, plug something else into that plug to make sure you didn't pop the circuit breaker

bad switch, bad motor capacitor, bad motor.

The thermostat is bad or out of adjustment.

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.

check for internal fuse or a start/run relay

see if you can find a new board the power failure fried it

The 265/277v units will not work in a 208/230v hotel without a transformer. Basically you do not want to get involved with that. When replacing your PTACs stick with the proper voltage. As far as a conversion kit, if one exists, the cost will put you right back at the cost of a new unit. If your hotel is wired for 208/230v it won't give the unit the power it needs to function properly. When looking for replacement units here's what you need to match (besides getting the proper BTUs):
Voltage
Unit size (make sure they fit in your existing sleeves)
Power cord configuration (the 265/277v will have a different power plug)
Good Luck!

Open the cover. In the bottom drip pan, there is a hole that is clogged. Just unplug it and it will drain.
