HeatingFurnace Repair Guide: Is It an Electrical Problem?

Your furnace needs electrical power to operate. It can be challenging to determine whether or not an electrical problem exists. If there is an electrical problem, it can be hard to locate. These are just two reasons why it’s important to call an expert for heating repair service. G&S Heating, Cooling & Electrical, Inc., has the certified technicians who can properly diagnose and repair your heating system no matter what the issue, so call us today.

Common Electrical Problems

Here are some of the more common electrical problems our technicians see:

Problems with Electronic Ignition

Newer furnaces use electronic ignition to light. There are two types of electronic ignition: hot surface ignition and intermittent pilot. Hot surface ignition is more widely used, but both need electricity to ignite the gas jets. With an intermittent pilot ignition, an electrical spark crosses a small gas jet; if the electricity isn’t flowing properly, the pilot won’t light. Hot surface ignition uses a probe that heats to a temperature that is hot enough to light the gas. The probe is encased in porcelain or silicone; the heat comes from two metal strips inside the probe that are electrified. Sometimes the metal strips can corrode, causing malfunction, or there can be an issue with the flow of electricity to the igniter. In either case, you’ll likely experience ignition failure or delayed ignition.

Circuit Breaker Issues

Your furnace is powerful enough that it requires its own circuit breaker in your home’s electrical panel. Circuit breakers can have problems, such as being undersized, loose or faulty. When there is an issue with the breaker, the electrical flow to your furnace may be interrupted, causing operational issues.

Problems with Wiring

Electrical wiring can fray, corrode, and loosen or disconnect, causing shorts, problems with consistent electrical flow and possible shutdown.

Heating repairs should always be left to trained professional, particularly on a combustion unit like a furnace. If experience problems with your furnace, call G&S Heating, Cooling & Electrical, Inc., immediately and schedule your heating service in Everett with one of our experts.
