Among the most frustrating things you may experience is when your furnace stops working properly. You have tried pressing the thermostat but nothing happens. Most of the time, the main problem of the furnace not working properly will happen at the beginning of the heating season. On the other hand, it is not always the case because of the varying variables that cause the problem. Here are some of the major reasons why your furnace is not working.
Insufficient Gas Supply
Most of the time, the furnace does not work because you think that the valve must only be partially turned just for safety reasons. Take note that the valve must be either all the way off or on.
Gas or electric, the furnace needs power for it to operate. If it does not work, try checking for a blown circuit breaker. In addition to that, look closely to see if there are wires that become corroded or been chewed by rodents.
Right before you call for a technician, some troubleshooting tasks can be done. You can check the thermostat to ensure that it is set to ‘heating’. Also, it should be set high enough in order to warrant kicking on. Remember that when the thermostat says ‘fan’, you need to make sure that you switch it to heating.
Blower Motor Issues
Your furnace should have an inspection window. Its flashing green light indicates that the blower system is working. However, if it is red or is not blinking anymore, there could be issues. If it happens, it is a great move to contact an HVAC service pro. This professional will inspect the transformer, control board, motor, and other important components, which might have malfunctioned.
No Pilot Light
To make sure that the blue light is properly lit, just check beneath the furnace. One of the most common occurrences is having them go out, but it can be remedied with just a strike of a match.
Dirty Air Filter
As a homeowner, you must be vigilant when it comes to changing the air filter. This is one great way to lower the energy bills, keep the furnace working, and most of all, to make sure that the indoor air is clean and pure.
The condensation pan on the furnace is responsible for collecting the excess water. When the reservoir is full, chances are the furnace would not function. Draining the pan is not a good solution knowing that it does not help solve the problems causing this. Find out if there are blockages that hamper the water from draining. It could also be the condensation removal pump might have gone bad.
These are just some of the reasons why your furnace is not working. As much as possible, ask for the services of professional technicians to make sure your furnace functions at its maximum efficiency. This way, you can be sure that you are getting the most out of your furnace.
