Why do furnace control boards fail?

Failed transistors: The transistors in the control board are susceptible to damage due to power surges, static electricity, and age. Transistors are often the first part of a control board to fail. Loose wiring: The vibrations of the furnace over the years can cause wiring in the control board to shake loose.

How long is the warranty on a control board for a furnace?

For most brands, the base parts limited warranty is five years to the registered warranty's 10 years. Parts limited warranties for heat exchangers may extend for life with warranty registration, or be limited to a shorter period, typically 20 years, without.

How do you diagnose a bad furnace control board?

Use some tape to keep the switch pressed down. If your control board has 120 volts AC going into it, then it has power.

How do you know if your circuit board is burnt out?

Signs of Overheating on Your Circuit Boards

Burnt, brown or blackened components.
Burn marks on the board substrate.
Delamination of the board.
That well-known “burnt electrical smell”
Cracks in the solder joints (typically caused by repeated overheating and cooling)
Broken traces.

How do you reset a furnace control board?

Follow these simple steps:

First, turn off the power supply to the furnace by turning off the breaker in the circuit box.
Locate the reset button on the furnace and press it to reset the furnace.
If the button is popped up, press it down.
Return the cover to the blower compartment and turn the power on.

How long does it take to replace a circuit board?

Circuit boards can be repaired in one to two days and cost hundreds of dollars less than buying new. Keeping repaired units on hand make for quick on-the-job replacements.

Do all furnace control boards have a fuse?

Your furnace's control board has a separate fuse that protects it from getting too hot. If someone is poking around your furnace and is not too careful, they could more wires so that they come into contact with the furnace's wire frame, causing them to short and blow the fuse on the furnace board.

What is the most common problem with furnaces?
