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.
Conclusion. Replacing a furnace control board is an essential aspect of maintaining the efficiency and safety of your home's heating system.
A heat exchanger replacement is often one of the most costly repairs in a furnace, and the expense can sometimes rival that of installing a new furnace. Typical replacement costs vary widely but can easily reach several thousand dollars, especially if labor costs are factored in.
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.
Depending on how technologically advanced your current furnace is, replacement costs for a new circuit board can run from around $300 to $1,200.
A circuit board replacements take 20 to 30 minutes. A furnace control board lasts 10 to 15 years on average.
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.
Usually, it is a quick fix, but sometimes the failure can be caused by a much bigger problem. The most expensive part of an AC unit to replace and repair is the air compressor.
The average furnace circuit board, also referred to as its “motherboard,” will last anywhere between 10 and 15 years.
Power Surges. Speaking of electrical discharge, another form of this can occur as a power surge. Power surges can come from faulty wiring, lightning strikes, or electrical overload. The energy from the surge can fry the furnace circuit board, making it unsalvageable.
If you're a pretty experienced DIYer, you can replace the control board on a furnace yourself for about $50 to $300, or the cost of the replacement circuit board. You'll need to pay close attention to how the existing control board is installed to make sure you wire the new circuit board correctly.
Faulty and loose wires can create electrical shorts that blow out a control board fuse. The furnace's vibrations can loosen control board wires over time and prevent them from sending information to the unit.
Replacement AC Circuit Board
The circuit board controls the operation of the blower fan motor as your air conditioner runs. The cost to repair this issue is typically between $100 to $800.
Installation Entails More than Just the Furnace
For a gas-powered furnace, a contractor must set up a gas connection and vent. Installing an electric furnace requires running wiring, adding a circuit breaker, or perhaps updating an electrical panel. Holes are often drilled for pipes and wires.
Yes, furnaces can last up to 30 years, particularly high-quality models with proper maintenance. Factors like regular servicing, timely repairs, and appropriate usage significantly impact their lifespan.
Even a slightly undersized furnace will accomplish the job the majority of the time. Taking things down a few sizes will more than likely solve some of your common heating problems like too high of a utility bill while half of your house is blazing and the other half is an icebox.
Start with a Visual Inspection
Often, circuit boards deployed in the field are damaged by electrical surges and there are telltale signs on the PCB. Look for a burnt spot, particularly on the power supply module or I/O and connectivity ports. Pay attention to cracked ICs, broken traces, and blown capacitors.
Three of the main reasons PCBs end up burning are: Extreme heat. Improper component spacing. Component failure or technician error.
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. It is usually located inside the blower compartment on the side of the blower motor.
