True Air question

[Daysu47]

Went out to do some work in the RV today, quite warm out, and decided to turn the AC on.
Moved lever over the cool setting, fan was on auto, speed was set on low..... then noticed the digital readout for the thermostat to note temperature was blank. ?????? Pressed both up and down buttons, nothing!!

AC would not come on, BUT, then moved the fan selector to On and fan came on, then moved the fan speed to high and the fan speed increased.

Everything else on the panel seems to work.

Facts..... Hooked to 30amp shore power, all 110v items work, all 12v items work. All is normal EXCEPT.........

Any ideas.

Thanks,

If I was having your problem I would unplug the t'stat and then replug it back in. If that fixes it, and it may, your done. If not go here: http://www.rvcomfort.com/rvp/rvp.php and download the service manual for your model. You will find some troubleshooting info that will probably help you get it fixed. Good luck

Im trying to remember but isnt there a fuse in the thermostat.

[Daysu47]

Fuse, yes, went back out and check the fuse, fuse Ok. Put fuse back in and now digital readout works now, BUT still no AC coming on.

Help!!

Have you gotten the service manual I mentioned in my earlier post?
Have you disconnected the t;stat and replugged it?
Take the cover off teh t'stat then removethe screws that old it to the wall so that you can unplug it. It may just be dirty/corroded connectors in the plug.

Did all recommended checks, nothing. Contacted TrueAir tech. and was given a electrical checks to do. Did check, looks like bad thermostat.

Will confirm Monday, will update.
