What To Do If My Heating System Keeps Turning Off

November 7, 2019

Border Sheet Metal & Heating has served Hayden and the surrounding areas with a broad range of heating services since 1942. One of the more frustrating problems for our clients is when their furnaces or other heating equipment turns off prematurely. If the heating equipment eventually turns back on, this is known as short-cycling. In some cases, homeowner intervention is required to re-initiate heating.

Dirty Furnace Filter

A dirty furnace filter is often the culprit, so check it first. If your filter has not been changed as needed, it will restrict air over the heat exchanger, which will then overheat. Upon detecting this excess heat, the system will disable the exchanger as a protective measure.

Thermostat Malfunction

Another common issue is that your thermostat is providing bad data to the furnace. Replace the battery, if applicable, and with the faceplate off, clean the unit, including cleaning dust out between the contacts. If that does not work, test a replacement thermostat after considering the next issue.

Thermostat Misplacement

Your thermostat can also be unreliable if it is misplaced. Poor positioning can mean that your thermostat is being affected by sunlight or just that it is not centrally located to your home. If your thermostat needs to be moved, it is best to seek professional assistance.

Oversized Furnace

It is important to size a furnace to its specific home. If your furnace was purchased and installed by the last homeowner rather than a pro, it is possible that the unit is too big. The home will heat quickly in this case, but that short cycle will create undue stress on the furnace and cause it not to last as long as it would in an ideal scenario.
