Heating your house with a reliable furnace is essential in the winter, when temperatures may drop below freezing. To keep it running smoothly and reliably, the system needs regular maintenance and adjustments, just like any other. Even if one takes all the necessary precautions, there is still the possibility that the furnace may malfunction.
The following is an exhaustive instruction on how to diagnose and fix problems with a furnace:
Verify That You Have Power
Does your furnace have access to electrical power? The following is an inspection and troubleshooting guide for the furnace. Check the temperature on your thermostat first. There is a switch that may be set to either “on” or “auto.” Put the switch in the “on” position. The fan ought to start spinning as soon as this is done. If it does, then you do not need to worry about electricity. In the event that it does not, the problem lies somewhere down the line with your power supply.
It’s time to check the fuse box.
Another method for determining whether or not there is power is to examine the fuse box and see whether or not it is still sending energy to the heater. Find the breaker for the HVAC system. Check to see whether it is turned on. In the event that it is not, turn the circuit breaker back on. In the event that the fuse has melted or become a different color, you will need to replace the fuse itself. Request assistance with the replacement of the fuse box from a company that repairs furnaces.
It’s time to check the air filter.
Over time, the air filter will become more contaminated. That’s one way to look at its function. A home’s furnace filter may get clogged with debris such as dirt, dust, and even hair from animals. If you don’t replace it, the dust and grime that have accumulated on it might cause a fire or cause the appliance to malfunction. Display your filter by holding it up to a light. A new one must be installed if there is no light penetrating the barrier.
Check Furnace Flame
You should not try to repair the flame in your furnace. Always seek the assistance of a professional. Having stated that, you may investigate the hue of it. It needs to have a wholesome blue color, with or without a yellow point at the end. The color blue signifies that it is burning correctly. Turn it off immediately and get in touch with a specialist if the light is orange, yellow, purple, or green.
Putting Another Match to the Pilot
If the flame in the furnace has gone out, you will have to ignite it again. Be cautious. Before doing anything of the kind, make sure you read the instruction booklet. 15 minutes before starting, make sure the gas is turned off. This will eliminate any gas that may be present in the region. From that point on, ignite the pilot light, and check to see whether it is functioning properly. No need to worry if you’re a homeowner who doesn’t feel comfortable doing this task on your own. This job is best left to a trained specialist.
Make sure the gas valve is open.
Check the gas valve’s (https://www.doityourself.com/stry/how-does-a-gas-control-valve-) position. Within a distance of no more than two meters from the heater, there must be a valve. Even though it’s very unlikely somebody has tampered with the valve, it’s still a good idea to check it again just in case. It’s possible that this is the problem, in which case you’ll have solved it on your own and avoided the expense of paying for a service visit from a professional.
Have a look at the boiler code.
Any furnace that was manufactured after the year 1990 will have a window that displays a light. It’s possible that this light is flashing a code. Take note of the key. Open a furnace’s access panels. On the inside, there must be a handbook that explains what each individual code implies. This will be useful information to provide the technician when you make the appointment so that they can better diagnose the problem.
Verify That Vents And Registers Are Working
Duct leaks from increased air pressure may be caused by blocked vents and registers, which can in turn lead to the need for maintenance of the heating system or even its premature failure. Remove any carpets, furniture, or other items that are covering these spaces that you already have. Even when you have the heating system on, the air just can’t move through the house. Blocked registers and vents are a symptom that ducting needs to be repaired. A professional from Frank H. Monroe Heating & Cooling and the like can assist with repairing damaged ductwork.
Lubricate the Motor of the Furnace.
It is common practice to use a lubricated blower when transferring heat from one location to another using the output of a furnace. In order to lubricate it, you must first stop the furnace by turning off the circuit breaker. Take off the panel that controls access. Find the blower in the room. Take the motor out of its housing by removing the bolts that are securing it there.
Find the oil ports, and then put a few drops of oil into each one using a dropper. One has to be attached to both the motor and the shaft. At this point, you should put everything away and restart the heater. After being oiled, the motor for the blower will function at a higher level of effectiveness.
Recognize When It Is Time To Contact A Professional.
When exactly one should get in touch with heating, ventilation, and air conditioning professional depends on the individual. In the end, you need to make the decision when you’re forced to do troubleshooting in a manner that makes you feel uneasy or dangerous. It certainly won’t hurt to have someone with experience take a check at your furnace. As a natural corollary, they will also be able to pinpoint the problem and find a solution much faster.
