Top 3 Reasons a Furnace Blower Will Quit Working
A blower on a furnace can stop working for a variety of reasons, including old age, excessive use, or electrical problems. It’s very common for this part to stop functioning correctly when its motor burns out or the bearings wear down. Fixing a broken blower on a furnace requires advanced knowledge and skills, so it’s always best to leave this task in the hands of a professional. If you don’t, you not only run the risk of damaging the entire heating system but also burning or electrocuting yourself.
1. Failed Capacitors
Your heater includes built-in capacitors that give it a power boost when you turn it on. The energy powers the blower motor, which in turn activates the heating system and warms the house. When the capacitors fail, the power required to turn on the heater becomes unavailable. The only way to fix this issue is to have them replaced by a certified technician.
2. Electrical Failure
When there are issues with the wiring or power source, the blower motor won’t get any juice. A blown fuse, a tripped circuit breaker, disconnected wires, or a broken thermostat are all potential culprits to electrical failure that can cause the blower to malfunction. A technician can inspect your system to pinpoint and fix the problem.
3. Circuit Board Breakdown
The control board acts as the furnace’s “brain,” telling the blower motor and other components what to do. In most cases, someone with specialized technical skills will have to repair a faulty furnace control board. The process often involves checking for loose wires, testing for continuity, replacing faulty components, and reassembling the entire unit, all of which are dangerous to those without the right skill set.
