Question about Honeywell Programmable Thermostat Heater
We had a power outage last night and now there is no display and won't turn on the heat. The fan will come on if it switch it to the ON position but won't start the heat.
Probably tripped a limit switch or a low voltage fuse would kill your display on the tstat, you should have battery power on your stat though.unless you have knowlege of electrical you better call a technician

1) red to rc and jumpered to rh
2) green to g
3) yellow or blue to y
4) white to w
to test: remove t-stat connect white and red - furnace should operate normally unitil you disconnect.

Normally, you should have 5 color wires: W-White, Y-Yellow, G-Green, R-Red and C-Blue.
The Blue wire is a common from the transformer on older systems, which is probably hooked to RC terminal.
Try this: Remove the blue wire and jump the RC to RH with the red wire and you will be fine. Blue wire should not be needed with the new thermostat.
This should also be stated in the instruction manual.
Hope this helps.

Sounds like a relay sticking. Possibly in the thermostat or possibly the furnace relay at the furnace. The next time it happens, unplug the thermostat from the wall. If the furnace still runs then it's the furnace relay.
Hope that helps...
