How To Solve Common Gas Furnace Problems



Understanding how your gas furnace/heating system operates is crucial whether you have a standard gas furnace that has some gas furnace problems. In order to know what to check for when there is a problem, you need to understand how the appliance functions in its most basic form.

Let’s examine a standard furnace and some suggestions for resolving some of its more frequent issues. (If any of these DIY procedures make you uncomfortable, seek a reputable expert for assistance. The ambiguity or a potentially dangerous furnace event are not worth a few bucks saved.)

Problem no.1: Verify That Your Thermostat Is Turned On

Although it may seem stupid, make sure the thermostat is set to “heat.” Moreover, check if the temperature is set at least five degrees higher than ambient. How frequently service calls are made without checking this might surprise you. Contact MMI Home Improvement for professional help.


Here are a few thermostat inspections you can perform on your own:

Step 1: 

Inspect the thermostat’s battery.  Your thermostat’s batteries might need to be changed. If the thermostat in your home is powered by batteries, make sure you replace them at least once a year or as needed.

While some thermostats use batteries, others are linked into the home’s electrical system. Moreover, when a battery has to be replaced, some devices that use batteries will occasionally show a low-battery indicator.

Step 2: 

Remove any dust or debris that may have clogged the thermostat by opening it and gently blowing it out.

Step 3: 

Check the date and time on electronic or programmable models to make sure they are accurate; the system might be set to a timer.

Check the breaker in step four. If on, shut off the breaker and look at the furnace’s fuse.

Problem no. 2 : Try To Reset The Home Circuit Breaker If The Furnace Isn’t Producing Any Heat.

This could happen for a variety of unimportant reasons. Moreover, verify that the thermostat is initially set to “Heat.” Then, try adjusting the dial a few degrees up or down to see if you can feel a change.

If nothing happens, examine if perhaps a fuse or circuit breaker was trip.

How To Check Your Own Breakers:

Find the circuit that manages the furnace by going to the breaker panel in your house. You’re checking to see if it’s in the middle or flung to the “Off” position.

  1. Check the breaker manually. It is turned back and forth.
  2. Verify that it remains in the “On” position.

Thus, the breaker will be reset. If this does not solve the issue, the circuit wiring or the circuit breaker itself may be defective. The following steps are for you if you have a digital multimeter:

Problem no. 3: Check And Replace Your Clogged Filter If Your Furnace Isn’t Producing Enough Heat

A furnace that has trouble producing heat is not the same as one that has mysteriously stopped functioning. Make sure the air filter is clean and in good condition because there are many advantages of clean vents, if not brand new, before attempting to fix a poorly functioning furnace that fails to heat the house adequately.

Examine And Replace Any Clogged Filters

This is a straightforward yet crucial step in furnace maintenance. However, a clogged filter is one of the most frequent causes of a broken furnace. Additionally, it’s the simplest maintenance task.

However, regular furnace filter replacement is a quick and easy activity that significantly enhances indoor air quality and protects HVAC components.

Find Your Filter 

The filter may be located in the intake on some furnaces. This most likely resembles a grate in a wall, floor, or ceiling. However, the furnace contains additional filters. Meesho supplier panel

Holding your filter up to the light can reveal whether it is time to replace it. You need to change the filter if no light can pass through. Another indication that it’s time to replace your furnace filter is a dusty, unclean odor coming from the vents when the blower is on.

Replace your furnace filter and make sure it is off. There should be no air escaping. Verify your filter’s pointing direction. Manufacturers design filters to catch material that blasts in one direction. Your filter’s efficiency may decrease if you install it upside down.

You can improve the air flow by clearing the dirt that accumulates on your filters.

Your air handler has to work harder to make up for the blocked air flow when your air filter has dirt. The decreased air flow through your heating and cooling system might increase your energy costs, overheat your heat exchanger, and cause it to shut down too soon.

Filters clean the air entering the furnace and the hot air returning to the house. When an airflow has restrictions by a dirty, clogged filter, heat and pressure eventually accumulate in the furnace.

Modern, more energy-efficient furnaces are attentive to the issue and frequently shut down before a clogged filter leads to further issues. However, the furnace will still operate for other units, but it will produce less heat and operate less efficiently.

Problem no. 4: Furnace Door Safety Switch

Checking the safety switch on the furnace door should be one of your first steps if your furnace won’t turn on. While you remove the access panel, a furnace door safety switch stops the fan and burner from turning on.

When the door is open, a safety switch on the furnace pops out. To turn on the switch and turn on the furnace, you must close the door.


Follow the detailed instructions on “How to Install a Furnace Door Safety Switch” if you find you need to install a new safety switch.

First, turn off the power.

Second step: clean the blower door

Wire the safety switch in step three.

Examine and validate the setup.


Regular system inspections, at least as frequently as the manufacturer advises, can stop a small fix from turning into a big job. Although DIY repairs can be rewarding and economical, it’s crucial to make sure you have the necessary abilities before doing any work on your furnace. You might require the support of a furnace repair expert if the advice provided does not assist you in identifying or resolving issues or if it is beyond your degree of expertise. Maintaining seasonal cleaning and tune-ups for your HVAC system is crucial. Until it breaks down, you may ignore the system.
