Computer-driven York gas furnaces provide amazing control and gas efficiency. We do not need chimney flue, just a standard vent that is typically on the side of the house. The vent releases nearly pollutant-free air. Things can and do go wrong and here are some steps to take that may restart your heat flow.
Check the Thermostat
Like a good “front man” the computer-controlled thermostat presents the appearance of command and control, however, it is the furnace, “the drummer” of the group, which “runs the show”. The thermostat sends signals to the furnace with instruction. Check your thermostat to ensure it is properly set to “heat”. If “heat” is not selected, then likely, the furnace does not know to initiate the heating process. There are many thermostats that are battery operated. Check and replace the battery, to better eliminate the issue. If you are unsure about the battery, turn the thermostat setting to fan. If the furnace fan comes on, then you have proper power and signal to the furnace. If not, then we may have found the issue.
Typical furnaces have two locations where power is required: the switch to turn it off and on and the circuit breaker. Usually, the power switch is located next to the furnace or on a panel on the furnace. Be sure the switch is “on”. If you experience the circuit breaker overload (trip), then you likely have an issue that will require one of Mehl Mechanical ‘s technicians.
Gas Control Valve
The gas control valve controls the amount of gas that is delivered to the burners. The igniter also benefits from the gas control valve. Most modern day furnaces utilize a Piezo sparking unit. If you hear a constant clicking when the thermostat is requesting heat, and the gas line valve is on, then you may need to fix or replace the control module; the gas valve may also have an issue that needs to be fixed. Again, a technician from Mehl Mechanical can assist you with this repair.
If you notice that your York gas furnace cycles on-and-off over several minutes, it is possible that the switch or controller may have a problem. These modules are computer-controlled and may require a reboot. The phrase “did you turn it off and on again” may work! If the problem continues, then give Mehl Mechanical a call and we will send one of our highly trained technician over to assess your furnace.
