Too cold to get burned...
 

:eek: I just had two power vents installed by the roofers. One of them nmentioned that they tripped a circuit. I think they have damaged the wiring ehrn they yanked the old power vent out.

Hhow can I test that the power vent works without waiting till summer? The thermostat has a low of 60 and high of 110 degrees.

I don't kow if this possible in your situation but how about a heat gun?

A heat gun or heat lamp near the tstat should turn them on. If it trips the breaker, trace the wiring to find the problem and repair it.
Good luck!
