In case you notice some level of heating inconsistency, then your furnace is certainly trying to indicate that there is a problem you need to sort out before things get out of hand.

One of the potential issues that are likely to come up with the thermostat is dead batteries. If you attempt to restart the unit without much success, then the batteries are dead and need replacement. If they are the problem, changing them and resetting the thermostat to heat should get things back to normal. Besides the battery issues, someone may have switched the thermostat off accidentally. Make sure to turn it on before deciding that it is a heater repair case. Yoru HVAC technician should have explained how the thermostat is wired for you to understand how it operates. If it is linked to the house’s electric system, you need to be watchful, affecting efficiency. Also, check the thermostat for clogging and dust accumulation as this could interfere with its efficiency. Depending on how the thermostat is, you may have to unscrew it to clean it properly. Once clean, make sure to set and program the thermostat appropriately. The date and time should be up to date to minimize errors. Lastly, check the circuit breaker and furnace fuse. If everything is in order and the thermostat still fails to respond, then you may have to call for furnace service expertise urgently.
