To determine if your furnace needs repair, check the circuit breaker in the home breaker panel. If you hear a rattling noise, look for a blown fuse. If you notice any of these symptoms, call a professional for a consultation. There are several steps to take to ensure your furnace is working properly.
Check for a gas smell
If you suspect your furnace is emitting gas, you should immediately call your gas utility company and get professional help. In addition, if you hear a hissing or roaring noise near the furnace, you should leave the house and call 9-1-1 immediately. Gas leaks are dangerous and should never be ignored.
Check for a rattling noise
If your furnace is making rattling sounds, check for loose connections or hardware. These may be causing the noise, and you can fix them yourself. For example, if the access panel of your furnace is loose, you can simply tighten it. If this doesn’t work, call a professional.
Check for a blown fuse
Before you begin doing any furnace repair, you may want to check the fuses in your furnace. This Furnace Repair is a relatively simple process. First, turn off electricity at the main electrical panel or the subpanel for your furnace. Then, place a multimeter on one of the fuses. A good fuse will have a reading between zero and five Ohms. If it reads more than that, it’s likely that the fuse has blown.
Check for a tripped circuit breaker
A tripped circuit breaker can indicate a faulty furnace. It can also indicate a faulty air duct. Be careful, however, because some wires can be live. Changing the breaker can be a complicated task.
Check for a blown belt
Before you start working on a furnace repair, you should make sure that it is turned off. This will prevent you from damaging the furnace by trying to turn it on when it is not running. You can check for this by looking at the filter and the access door. Make sure that nothing is blocking the air intake or the exhaust. If you see ice on the pipes, this could be an indication of a more serious problem with the furnace. It is best to get your furnace checked by a professional so that you can avoid any potential damage to your home.
Check for a blown control board
When doing furnace repair, it is important to check for a blown control board. Usually, the board is located near the blower assembly. If you notice burn or melting marks, blackened parts, or any strange smells, the board has likely blown. If you have these signs, you should replace the board.
Check for a blocked air intake
If your furnace has been running erratically, it may be the result of a blocked air intake pipe. You can check the air intake pipe yourself or call a HVAC professional to clear it for you. This pipe is located outside, near the foundation, and can sometimes be clogged with leaves and other debris. Once the pipe is clear, you can do furnace repair.
