Integrated Furnace Control Board (IFC)

What causes furnace circuit board failure?

Voltages and surges can affect the function of the circuit board. Dirt can also cause a circuit board to fail--as dirt and dust build up and cause an insulated layer on the board, creating heat which will cause the board to overheat and burn out.

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 do you know if your furnace motherboard is bad?

Here are signs you may have a malfunctioning furnace control board: Uncomfortable temperatures: If your furnace starts to make you either too hot or too cold, and the thermostat settings seem fine, then the problem might be a control board that is turning components off too soon or letting them run too long.

How do I replace my IFC on my furnace?

Click on the door switch. And click remove tape. Next we want to replace the cover on the unit

How much does it cost to replace a control board on a furnace?

A furnace control board replacement costs $300 to $650 on average. A furnace circuit board or motherboard costs $50 to $300 for the part alone, plus $250 to $350 for replacement labor. HVAC contractors charge $75 to $150 per hour for furnace repairs.

Can I replace my own furnace circuit board?

If you've determined the circuit board is the cause of your furnace problem, it's a relatively easy part to replace. The circuit board is usually located in the furnace's blower chamber near the bottom of the unit. This is where the circulation blower fan motor is mounted.

How can you tell if a circuit board is blown?

Examine the circuit board and search for signs such as crushed components, bulges, damaged wires, cracks, misplaced or extra solder, burn marks and scratches that indicate that the board is either bad or requires replacement and professional assistance.

Can you bypass the circuit board?

You can bypass the AC circuit board, but it is highly recommended that you do not do it without a solid reason. If you must, only let a trained technician do the job.

Where is the fuse on the furnace control board?

And typically that's going to be located in the lower compartment. So you have an upper compartment

Where is the furnace reset button?

All furnaces are equipped with a reset button. They are generally red or yellow and are located inside the blower compartment. The reset button is a safety feature that will shut down the furnace when a problem is detected, often a hot or overheating furnace, before it trips the circuit breaker.

How many times can I hit the reset button on my furnace?

Don't hit “reset” more than twice. The process pumps oil into the burner chamber, where it can accumulate if you have no ignition. Then when the furnace finally does start, it can do so explosively. So if the button won't reset, or quickly pops up again, it's time to call a professional repair service.

What is the most common problem with furnaces?

The most common problems with furnaces are:

Dirty ductwork.
Old filters.
Faulty starting mechanism.
Broken blower components.
Malfunctioning heat exchanger.
Bad Limit Switch.
Thermostat in need of repair.
Tripped circuit breaker.

Is it worth repairing a furnace?

Your Furnace Is Old Consider 15 years a good cutoff when deciding if you'll replace or repair a furnace. If your furnace is older than that, it's likely time to replace your unit instead of investing hundreds or thousands of more dollars into repairs.

What are common home furnace problems?

What goes bad on a furnace control board?

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.

Why do modern furnaces use IFCs?

Many modern gas furnaces use electronic modules or integrated furnace controllers (IFCs) to control the operation of the furnace. These controllers often have dual-in-line pair (DIP) switches that can be switched to re-program the furnace to make it more versatile.

How much does it cost to replace a furnace thermocouple?

Thermocouple. If your furnace is an older model with a pilot light, it relies on a thermocouple to shut off its gas valve if the flame goes out. The average cost to repair or replace a thermocouple is $100–$250.

How much does it cost to replace a circuit board on an HVAC system?

Air conditioning circuit board replacement costs $150 to $700 if the AC unit is not under warranty or $100 to $300 for labor if under warranty. AC control board prices are $50 to $400 on average for the part alone, depending on the brand, type, and model.

Is it better to repair or replace a furnace?

If there is a significant difference, then it's time to replace your furnace. Repair: If your furnace system is less than 15 years old and the cost of repair is less than half the cost of replacement. Replace: If your furnace system is more than 15 years old and requires a costly repair to maintain efficiency.
