Alamolady Report post Posted January 8, 2015 On arrival to winter site in south Texas our thermostat froze up. Replaced fuse, reset. Still not working. Replaced thermostat. Only can see one unit out of three on read out. Will quit and freeze at any time. Any suggestions on how to trouble shoot the problem? Have 2010 Tiffin Phaeton QTH.

wolfe10 Report post Posted January 8, 2015 Shelia, By freeze, do you mean "it quits functioning"? What brand and model thermostat? of A/C? Share this post Link to post Share on other sites
dickandlois Report post Posted January 8, 2015 Shelia, The information Brett ask for would sure help. You mentioned that you can only see the status of on unit on the display, hard to really tell, but do you have florescent lights that are on? The control circuits for the heat and AC units can be affected by noise. Did the heat work before you arrived at your winter site? If you disconnect from the shore power connection and run the generator - will the heat work? Rich. Share this post Link to post Share on other sites
