Had a troubleshooting job the other day, apparently a couple of the old baseboard heaters liked coming on at 80+ degrees even when below the "Medium" setting.
My suggestion was to replace the T-stats (intergral "on the unit" type) but I discovered a screw that would adjust the make and break position on the Dial at ambient temp. It had red dye on it to signify any tampering. The T-stats work fine otherwise.
My question...
Do I replace the T-stat or merely adjust them with this screw they have?
Blissfully Ignorant,
