FURNACE REPAIR NEAR ME: Gas Furnace Pressure Switch Problems

Your gas furnace has multiple safety switches. The pressure switch is the one that’s more likely to cause a problem. Even then, you can expect your pressure switch to last for at least 10 years. Replacing it will typically cost around $250.

What is a furnace pressure switch and what does it do? 

A furnace pressure switch is a safety component that’s located near the motor. Keeping everything in check alongside the control board, this automatic safety feature would shut your furnace down if it detects negative pressure coming from the draft inducer motor.

A properly working pressure switch keeps your unit from running in an unsafe condition. If the pressure switch of your furnace fails, your furnace can’t safely operate. So it’s important to troubleshoot pressure switches if you’re experiencing any issue.

Gas Furnace Pressure Switch Problems

Your pressure switch may not close, or it may stop working at all.

The most common problems that homeowners deal with are:

1.  Blockages, including a blocked flue pipe 

This is less likely to happen when it’s cold and your furnace is being used. However, during the warmer months, there are creatures that can temporarily reside in that space.

Any obstruction in the port that leads to the collection chamber may also cause pressure switch problems.

2. A stuck or damaged diaphragm 

A stuck diaphragm can be easily fixed by tapping the casing. But you may need to replace it immediately if you hear ‘flapping’ sounds reminiscent of a flat tire.

3. Damaged pressure switch hose 

Over time, the pressure switch hose can get damaged or worn out. It can also fill with water due to heat going down from the flue and into the pipe.

Tell-tale signs your pressure switch has failed

As a homeowner, you’ll notice right away if your pressure switch isn’t working as it should.

You may hear unusual noises when your furnace is attempting to start. You won’t get any gas, too, and only room-temperature air will come out of the vents.

However, airflow without heat is also caused by a faulty furnace ignitor, so this is something you may have to check as well.
