The tools needed to fix common thermostat problems include a compressed-air cleaner, a soft brush and a torpedo level. When properly used together with basic thermostat repair knowledge, these tools help to efficiently eliminate simple thermostat malfunctions.
A furnace may fail to produce heat due to a dirty thermostat. In this case, a compressed-air cleaner is used to clean the thermostat of dust and dirt buildup. A soft brush aids in scraping away any stubborn dirt the air cleaner cannot remove.
When the room temperature fails to match the preset temperature on the thermostat, it implies that the thermostat is crookedly installed. To fix this, a torpedo level is used to set the thermostat level.
