What to Do When Your Furnace Breaks Down: A Homeowner’s Guide

When winter hits, a functioning furnace becomes essential for keeping your home comfortable and safe. But what happens when your furnace unexpectedly breaks down? Here’s a quick guide to h2troubleshoot and resolve the problem or know when to call in the professionals at Riverside Heating and Air Conditioning.

Step 1: Check Your Thermostat

First, ensure your thermostat is working correctly:

• Set the thermostat to “heat” mode.
• Make sure the temperature setting is above the current room temperature.
• Check the battery, and replace it if needed, as dead batteries can prevent the thermostat from signaling the furnace to turn on.

Step 2: Inspect the Power Supply

Sometimes the solution is as simple as restoring power:

• Check the circuit breaker for any tripped switches connected to the furnace.
• If your furnace has an on/off switch nearby, confirm it’s in the “on” position.

Step 3: Check the Furnace Filter

A clogged air filter can restrict airflow, causing your furnace to overheat and shut down:

• Turn off your furnace, remove the filter, and inspect it.
• If it’s dirty, replace it with a new filter. Regularly changing filters every 1-3 months is ideal for keeping your system running smoothly.

Step 4: Confirm the Pilot Light is on (if applicable)

If you have an older furnace with a pilot light:

• Inspect the light to see if it’s out.
• If it’s off, relight it following the manufacturer’s instructions, or call a professional if you’re unsure.

Step 5: Look for Blocked Vents

Blocked vents can trap heat and force your system to shut down:

• Go room to room to ensure all vents are open and clear of obstructions like furniture or rugs.

Step 6: Check for Error Codes

Newer furnaces often have LED displays with error codes:

• Refer to your furnace’s user manual to understand the code, which can help pinpoint the issue.
