Service through HVAC maintenance agreements and monthly air filter changes can typically prevent a furnace from continuously running. However, if it seems like the furnace has been running for an hour or longer without stopping, you may need some tips to help you now as you wait for that professional service.
Sometimes a furnace blower will not turn off because there is a mechanical or electrical problem with the system. When a furnace fan won’t shut off, this unnecessarily consumes electricity and produces unneeded wear and tear on the furnace itself. Troubleshooting your furnace and knowing what to do when it won’t shut off could help you save money on your winter heating costs and future furnace repairs.
If the furnace has been running for a while and won’t stop, these troubleshooting steps might help you find the cause and a solution to the problem:
If none of the above stops the furnace running, you may need to manually shut it down. Once the thermostat heat settings are shut off, go to the circuit breaker and turn off the power to the furnace. Its fan and blower will stop running. At this point, it’s time to call for a professional technician to find the cause of why the furnace wants to cycle continuously.
