Why Does My Furnace Keep Turning Off?

Furnaces that keep shutting off after only operating for a few minutes are short-cycling. Your furnace is doing this to protect itself from overheating and failing completely. It’s actually a safety mechanism built into the unit. Check these four items to correct the problem and prevent a complete system breakdown.

1. The Filter is Dirty

Regular filter replacement is a must if you want your temperature-control equipment to operate correctly. Filters trap dirt and prevent it from entering the system. A dirty filter can block airflow and overheat the equipment. Replace the filter as recommended by the manufacturer or a trained technician. This is usually once every three months at the least.

2. The System Needs to Be Cleaned

It’s just a fact of life that equipment gets dirty and needs to be cleaned. Too much dirt buildup can cause your heater to malfunction. A seasonal maintenance call will take care of the problem. All Temp Co., Inc. provides maintenance tune-ups for homeowners located in Harrisburg and the surrounding areas. Our technician will check and clean each area of your system. Let us know you want an annual checkup.

3. The Vents Need to Be Opened

People commonly close vents in rooms that are rarely used. However, some systems will shut down when too many are closed at the same time. The closed vents slow the blower down, and the equipment can malfunction. Check your vents periodically to ensure they aren’t blocked by furniture, drapes or d├ęcor. Consider installing a zoned system to help you manage air distribution in your home.

4. The System Is the Wrong Size

Oversized heating systems are a waste of money and energy. They will heat your home quickly and cycle on and off too often. If the system is old, a replacement can solve the problem. If the system is new, contact professionals about a remedy.
