Blank thermostat
I have a totaline thermostat that just went blank. I checked the circuits and all were on. I reset them anyway but still blank. I took the thermostate cover off the wall and tried it on another floor and it worked, so I don't think it's the thermostat. From reading the forum it seems it's either a blown transformer or a blown fuse. I don't know where the fuse would be or how to determine if the transformer is bad. Any info on this would be very helpful and appreciative. Thanks.

Do you have a meter?
Take a reading between R and C, should be about 24 volts.
What it the make and model of the furnace? The fuse most of the time is on the board of the newer equipement.
