Detached 2-car frame garage with only 2 tiny gable vents. Way too hot in summer. I installed a 12" exhaust fan in a window frame many years ago.
The thermostat is a series of metal blades (bi-metal) and a pair of contact points like in old cars, mot'cycles. It wouldn't shut off last summer, I filed the points down like I'd done years ago with cycles. Worked for last season.
This season I file 'em down, add some dielectric grease, it works for a few hours, then fails to shut off.
Markings on the tstat: BIMET 70F A76 FP 21 6-22 HOOD
Any chance of picking up a replacement tstat?
Any tips, suggestions, ways to "fix" the old tstat?
TIA, Puddin'
