What do you mean rebooting? Is screen going blank and then coming back on?

Do you have a volt meter to check to see if we are losing the 24 volts from air handler between R and C wires?

no :(
HVAC Technician: airheatman, HVAC Technician replied 2 years ago

The only reason screen should go blank is if the thermostat loses power.This could be a bad furnace transformer bleeding down under load but we would need a meter to check this.

You may have to get a technician onsite with test equipment. Meanwhile would you like to see if we can make heat come on temporarily to warm up until you can get a tech out?

How?
HVAC Technician: airheatman, HVAC Technician replied 2 years ago

remove front section of thermostat by pulling straight out and off of sub base, Then tell me what wires you have connected to what terminals on sub base.

red to rc
white to o/b
yellow to y
g to green
and blue to c
HVAC Technician: airheatman, HVAC Technician replied 2 years ago

Loosen the RED and White and move the white over and stick in slot with RED and tighten .See if heat comes on.

Customer reply replied 2 years ago
no
HVAC Technician: airheatman, HVAC Technician replied 2 years ago

OK if heat does not come on when connecting Red and white, we have an issue at furnace.Again this could be a transformer.

If you can get a meter we can troubleshoot the furnace issue .

You can get an inexpensive one at Walmart for about 15 bucks if you would like to troubleshoot and I would be happy to guide you.

Please give me a refund as I am not satisfied with this whole experience
HVAC Technician: airheatman, HVAC Technician replied 2 years ago

Ok I wish we were able to get you some heat, but without a meter to see why we are not getting signal to thermostat or heat to energize bypassing thermostat not a lot we can do.
