Does the power light come on?
If yes, then you can do a reset as below:
There is a master switch on the bottom left of the control board. Slide that to 'off' position.
Then press the hot and cold switch/key together and then slide the master switch back to 'on'.
Please put your response/observation here if that does not work or there is power light as asked on top.
Thanks

Not a computer question.

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.

The tv power supply board have dead components parts call capacitors most likely.U have all the tools and understanding basic electronic also can do basic soldering too?The tv power supply board that the board where the power a/c cord plug into it.Take the tv aparts and check the tv power supply board carefully for dying and dead capacitors parts.These capacitors parts are alway bulges up or puffing up on to it tops.Must replaced all these dying capacitors parts are bulging up ur puffing up on to it tops.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole new refurbish power supply board for the replacement.

To resolve the issue, follow these steps:
1. Turn off the master power switch, disconnect the power cord, and then wait a short time.
2. Reconnect the power cord, and then turn on the master power switch. 3. If the previous steps don’t resolve the issue, the lamp might be at the end of its life. (double check that you get a good one lamp, and that are installed correctly)
4. If your projector still doesn’t turn on, turn off the master power switch, disconnect the power cord, and then contact your local repair shop for Fix the Board on the prjector

you have the white wire on the wrong terminal put it on the same terminal as the red wire on the capacitor and you should be fine,

First off, you need to unplug power from the unit before handling anything on it, not just the master switch on the control board. There is still live power being fed to the unit while it is plugged in!
Now, the clicking sound you are hearing is a faulty relay on the control board. You have to replace the control board. The new ones are available from Amana/Goodman Mfg.. You will find, assuming you have more of these, your other units are going to start doing the same thing. It will be the same problem. When they send out the new control board, make sure you program the board. They no longer come pre programmed. It is actually a huge improvement on the older control board upgrades. Hope this helps, I have 140 of these in my hotel, I know them all too well. Let me know if you have any other questions and please rate this as a fix ya.

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.

Reset the unit to factory setting by take the master switch off of 10 sec.
Then press and hold the cool and heat button down while turning the master switch back on.
