Is your furnace not responding to your thermostat?
There are a few things that might crusade your furnace to "ignore" a call for heat from the thermostat. I have addressed them below and propose a few things y'all can attempt to fix the problem. However, when in incertitude, consult a licensed HVAC technician to assistance yous.
Filter – The most common cause of furnace problems is a dingy filter. If you furnace filter is clogged, the airflow will exist restricted. As a result of this restriction the exchanger in the furnace volition overheat and automatically close off for rubber reasons. If yous ready your thermostat for heat and the blower comes on only with no warmth, your exchanger may accept close off. Changing your filter will assist keep the mechanical components of the furnace complimentary of grit and clay and may prolong the life of the system. A bones filter should be changed one time and month and a pleated filter should exist checked in one case a month and changed at least every three months. If yous home is located in an surface area where pollen can be an result, such as New Jersey or the Eastern seaboard, y'all may need to change your filters more oftentimes than in a less dusty area.
Thermostat – If your thermostat isn't properly functioning, your furnace won't respond in the correct manner. First and foremost, cheque to be sure information technology is set to "heat". This simple step is oftentimes overlooked. Brand sure information technology is deeply attached to the wall and no wires appear loose or frayed. If information technology is a programmable unit, exist sure the time and date are right. Also, be sure to check the batteries then in the effect that there is a power failure yous won't lose all your settings. Test information technology by setting the temperature five degrees college than the temperature of the room; run across if it comes on (any programming can be overridden by holding the temperature up arrow and holding information technology for several seconds until the called for temperature rises: and so hit "hold"). If you hear the fan respond you know that your thermostat is functioning as it should.
Electric – Be certain your crimson emergency switch is on; It may accept accidentally been switched to the off position over the summer. Next, bank check the circuit breaker at your electric breaker console. Check for a blown or tripped fuse. It'south a good idea to scan the console for whatsoever loose wires or show of other issues. If you detect anything more complicated than a tripped fuse yous should call a qualified heating repair technician.
Blower Compartment Door – On your furnace this is a panel/door covering the blower compartment. This door, when properly installed, trips a switch that signifies to the system that is sitting correctly. If the switch isn't engaged, the system volition not reply.
Pilot – Nearly furnaces have an automated electronic ignition. If yours is not electronic, consult your furnace owner's manual and lite it.
Drain Lines – If you accept a high-efficiency furnace, inspect your drain lines and brand sure they are complimentary of sediment and any debris build-up. Flush the hose out with a bleach solution if information technology appears dirty.
Outside Vent – If yous take a furnace that vents out the side of the business firm, check that outside vent and run into if information technology is free of leaves or other debris. Sometimes birds and rodents use vent openings to make a nest so this step is particularly of import in the spring and summer months. Ensure this hasn't happened. Your furnace needs to vent properly to part properly.
