3 Signs of a Malfunctioning Furnace Limit Switch in England, AR

Every furnace must have a limit switch. It’s a safety device that monitors the system’s interior temperature and shuts it off once it becomes too hot. Given this description, it’s essential to figure out when your furnace’s limit switch doesn’t work as it should. Here are three signs of a malfunctioning furnace limit switch in England, AR:

Short-Cycling Furnace

The term “short cycling” refers to an abnormal behavior when your furnace turns off before completing one of its heating cycles. It can then turn on again shortly after, leading to an erratic pattern of operation that threatens to overwhelm and seriously damage your furnace.

If your furnace overheats, it may end up shutting down. Once its limit switch stops working, there will be no check for overheating. Therefore, short cycling may follow as a natural consequence.

Many other things, like inadequate airflow, may also cause short cycling. Make sure that you can rule out these other possibilities before blaming your furnace’s limit switch for what’s wrong. The best safeguard against short cycling is to give your system annual professional heating maintenance.

Nonstop Blower Operation

Your furnace’s blowers push air through the system and into your home. Without a working limit switch, they may end up working ceaselessly.

Increased Energy Bills
