How a pro relights a gas furnace

First, conduct a safety check to see if there’s a leak or signs of carbon monoxide. Unless you are a master do-it-yourselfer you should call an experienced furnace technician to determine why the ignition conked out and how to restart it.

There are several potential reasons for the failure. They could be major or minor problems.

An older furnace that has a pilot light could be experiencing drafts, thermocouple deterioration or supply snags. 

Even new furnaces with electronic ignitions can have worn parts or electrical snafus.

A good technician will safely restart the system and find and correct the cause. 

Troubleshooting

After checking for safety issues the tech will review a checklist of possible reasons why the ignition or pilot light failed:

• Drafts or dirt in the lighting mechanism

• Fouled burners

• Worn thermocouple

• Low gas pressure or inadequate gas supply

A tech has the tools, parts and training to correct the problem and get your home or business safe and warm again. And you have the peace of mind knowing that the job was done by a professional who guarantees the work.
