HVAC Questions? Ask an HVAC Expert for Answers ASAP
The thermostat was installed last fall--new home--and worked perfectly all winter. Today I was trying to switch to air conditioning/cooling, I tried to do it manually by pushing buttons on the display. When I switched the "system" setting to "cool" instead of "heat", that is when I lost all power to the thermostat display.
it is a Maytag, sorry I cannot locate the model number.
If it is a short in the AC unit then probably I should just call my original HVAC installers tomorrow and get them to fix it.
You are correct.There is a 3amp fuse on the circuit board in the durnace that blew to protect the system.The thermostat wire that goes outside to the ac unit can get ice damage, rodents, weed wacker....or hooked up wrong.I am confident they will find a minor wiring issue and replace a 3 amp fuse.I really wish you well and if you have further questions on this just let me know.Billy
thanks, XXXXX XXXXX that is the problem. It is true that they originally installed the HVAC incorrectly since they already had to come on a service call and fix the fan speed.
Meanwhile, is there a way to turn my heat back on?
That's beyond my skills unfortunately and also I don't have a spare fuse anyway. I guess I will just haveto get someone here tomorrow to fix it.
