With a little DIY experience, you can do furnace troubleshooting & repair by yourself.
Whether you own a conventional gas furnace or a high-efficiency gas furnace, understanding genuinely how the furnace or heating system is working is so essential. You have to understand the simple workings of the appliance, so you know what to look for when you need furnace troubleshooting & repair.
Let’s have a look at a conventional furnace and tips to solve its more common furnace problems.
Check the thermostat to be sure it is ON
It may sound ludicrous, however, check the thermostat to make sure it is set on “heat” and that it is set more than five degrees above the room temperature. You would be surprised how many furnace troubleshooting & repair calls are made without checking the thermostat.
Here are some thermostat checks to manage yourself:
Step number 1 – Check the battery on the thermostat. Maybe you need to change the batteries on the thermostat. If your house’s thermostat unit runs on batteries, make sure that you change them at least once a year, or as needed.
A few thermostats are wired to the electrical system, while others use batteries. How is your thermostat powered? Sometimes the thermostat that uses batteries will flash a low battery symbol when they need a replacement. Before calling furnace troubleshooting & repair experts, make sure your thermostat’s battery is full.
Step number 2 – Open the thermostat and gently clean any dust and debris that clogs it.
Step number 3 – Ensure that the date and time are correct on programmable or electronic models – the system can be on a timer.
Step number 4 – Check the breaker. If it is on, turn off the breaker and check the fuse for the furnace.
The furnace is not providing heat – Try to reset Circuit Home Breaker
There are a lot of minor reasons why this can happen. First, ensure that the thermostat is on “Heat.” Later, try to move up the dial or down some degrees to check if a considerable difference is felt.
If there are not any results, check to see if a circuit breaker or fuse is blown or tripped.
How to check home breakers
Go to the home circuit breaker and find the circuit which controls the furnace. You check whether it is thrown to the “OFF” or it is in the middle.
You can check it manually. Flip it back and forth.
Ensure that it stays in the “ON.”
The process will reset the breaker. If it is not still operating, you probably have a problem with the circuit breaker itself or the wiring in the circuit.
The furnace is not providing enough heat – Clean or change the clogged filter
A furnace that struggles to produce heat is a different matter from the one that has stopped running somehow. If the furnace provides you with the poor heating performance that does not mean enough to heat the house sufficiently, first make sure that the air filters are not clogged with dust and debris and they are in good condition if they are not new. Cleaning or changing the air filter regularly will avoid you spending money on furnace troubleshooting & repair.
Check and change the clogged air filter
It is an easy but essential component of furnace troubleshooting & repair. One of the most general reasons to have a furnace not working is a clogged air filter. It also occurs to be the easiest maintenance chore.
Replacing the air filter is a simple easy and quick task, and it goes a long way in prolonging the lifetime of the HVAC parts and increasing the indoor air quality.
Locate the filter – A few furnaces have their filter in the intake. It looks like a grate on a floor, wall or a ceiling. Other filters dwell in the furnace itself.
Check the filter – You can check the filter by holding it up to the light. If there is no sunshine through, the filter requires changing. Unpleasant odors from the vents when the blower is on is another sign that shows you the furnace filter needs to be changed.
Replace the filter – Ensure that the furnace is turned off. No air has to be coming out. Check the direction of filter points. Installing the air filter incorrectly can decrease efficiency.
Cleaning the debris which builds up the filter will help the airflow. When the air filter is clogged, the air handler has to run harder to compensate for blockage of airflow. In addition to increasing the utility bill, the reduced airflow through the heating and cooling system may result in overheating the heat exchanger and shutting off too quickly. Modern and efficient furnaces are not more enduring to the issue. Probably, other air conditioners are going to keep functioning, but they will run with less efficiency and heat.
Safety switch on Furnace Door
If the furnace is not running, one of the immediate things you have to do is check the safety switch. A furnace door safety switch avoids the fan and burner from coming on while the access panel is removed.
Furnaces own a safety switch which pops out when the door is removed. The door has to be in place for the switch to be activated and for the furnace to run.
If you find that you need to install a new safety switch, step by step follows these instructions below:
Shut off the power
Prep the blower door
Wire the safety switch
Check and test the installation
Clean the area around the furnace clean and keep unobstructed
It may sound like a visible tip. However, some people with busy lives forget to take care of areas of their house like a basement. A basement may become snafued, which leads to the area beside furnace being filled with various possessions and debris. Cleaning does not only make the furnace work better, but it also looks better.
Prevent storing flammable substances or materials next to the furnace. Crowding the furnace will lead to accidental fires, significant damages to your property and danger to you and your family.
Although it seems convenient to store everything there for the summer, take into consideration the possibility that you can forget any items you have left on or next to the furnace. Do not take chances; the furnace must have a special room to operate safely.
Besides, clean and vacuum regularly around the furnace. While you have removed any or all the flammable items from the area, do not forget that dust and lint may build up and create a fire hazard. A considerable amount of lint and dust can cause the filter to be clogged sooner than regular, and it will require more frequent replacements.
