thermostat display blank and furnace not working

[Janie_Ryan]

My thermostat display is blank. I've checked fuses, . power to trailer (both battery & electric. I've taken thermostat cover off to see if requires batteries ( it doesn't ). Help. Need heat this weekend.

Checked the fuse one more time. That was it. Thanks

12V DC power comes from a fuse in DC dist panel

If thermostat display doesn't light then fuse is blown OR t-stat needs reset.

May as well post the brand and model number.

unplug the phone line at the bottom, wait 1 full minute and plug it back in. That worked for ours. Also there is a reset procedure. What brand and model thermostat is it?

There may be a fuse, atc type on the furnace motherboard that you would access from the outside panel. Look for a broken or loose wire.
