Why is my heater not working? Tips for the most common furnace problems

Nothing is more unpleasant than waking up in the middle of the night with a cold. If all you need to do is pull the covers up, that's one thing. If your furnace isn't working well or at all, it's a different matter. You can troubleshoot and fix your furnace yourself if you have any do-it-yourself experience. Understanding how the furnace/heating system operates, whether you have a traditional gas furnace or a high-efficiency gas furnace, is essential. You should be familiar with the appliance's basic functions, so you know what to look for if anything goes wrong.

Let's take a look at a traditional furnace and some tips for dealing with the most popular issues:

1. Make sure your thermostat is turned on.

Check the thermostat to make sure it's set to "heat" and at least five degrees above room temperature, which might seem ridiculous. You'd be shocked how many service calls go out without this being reviewed!

Here are some thermostat tests you can do on your heater repair:

Step 1: Check the thermostat's battery. Your thermostat's batteries may need to be replaced. If batteries power your thermostat, make sure you return them at least once a year or as required.

Step 2: Remove any dust or debris that has clogged the thermostat by opening it and gently blowing it out.

Step 3: On electronic or programmable models, double-check the date and time, as the device can be set on a timer.

Step 4: Examine the circuit breaker. If the breaker is on, turn it off and check the furnace fuse.

2. If your furnace isn't producing heat, try resetting the circuit breaker in your home.

There may be a variety of minor causes for this. To begin, double-check that the thermostat is set to "Heat." Then, move the dial a few degrees up or down to see if there is a significant difference. If nothing seems to be wrong, check to see if a circuit breaker or fuse has been tripped or blown.

How to test the Home Breakers:

Step 1: Test the breaker manually. It can be flipped back and forth.

Step 2: Ascertain that it remains in the "On" spot.

3. Safety Switch on Furnace Door

One of the first things you can do if your furnace isn't working is to check the safety switch on the furnace door. While the access panel is removed, a furnace door safety switch prevents the fan and burner from turning on. When the door is removed from a furnace, a safety switch pops out. For the switch to be triggered and the furnace to run, the door must be closed. 

Follow the step-by-step directions on "How to Mount a Furnace Door Safety Switch" if you discover you need a new safety switch.

Step 1: Switch off the gas.

Step 2: Get the blower door ready.

Step 3: Attach the safety switch to the circuit.

Step 4: Inspect and evaluate the setup.

4. Once a year, oil the furnace blower.

When preparing your furnace for the winter, make sure that all of the components of your heating system are clean and functional. The primary purpose of the furnace blower is to extract heat from the furnace and disperse it across the home. Keeping your furnace's blower lubricated will help it last longer.

Here are informative and straightforward steps to follow. How to Oil a Blower Motor in a Furnace:

Step 1: Turn off the circuit breaker that supplies the furnace's power at the main electrical panel.

Step 2: Remove the access panel from the furnace by unscrewing the screws with a screwdriver.

Step 3: Look for the blower motor assembly near the furnace's foundation. With a wrench, remove the bolts that secure the blower motor to the furnace's main assembly.

Step 4: Look on the side of the blower motor housing for the set screw. Remove the bolts and set them aside. Remove the motor from the housing and set it aside.

Step 5: Examine the motor and shaft for oil ports.

Step 6: Add 2–3 drops of oil to each terminal.

Step 7: Switch on the furnace. With fresh gasoline, the blower motor should perform better.
