How Much Does Furnace Control Board Replacement Cost? [2026 Data]

Furnace control board replacement costs anywhere from $50 to $900 on average, but most people pay $500. Labor costs in your area and the specific type of control board you buy will impact your total price. Keep reading to discover more factors you should include in your budget for furnace control board replacement.

Furnace Control Board Replacement Cost Breakdown

Furnace control board replacement costs typically range from around $300 to $700, which will cover the cost of the new control board and professional installation. The type of control board may also influence the project total.

Materials

A new furnace control board costs about $50 to $300, but the cost will depend on the complexity of the control board and the brand. On the lower end of this range, you’ll find simple control boards and universal parts, meaning they are designed to work for a wide range of furnace brands. 

On the higher end of the range, you will find integrated control boards, which are more complex and offer more functions, and original equipment manufacturer (OEM) parts. OEM refers to parts made by the original maker of the furnace. While they may be more expensive, manufacturer parts are specifically designed to work with your furnace system.

Labor

Hiring a furnace repair pro to replace the control board costs about $150 to $450 total. The contractor you hire may also charge by the hour, and you can expect to spend about $50 to $150 per hour.

Additional Costs to Consider

The cost to replace a furnace control board primarily depends on the cost of the replacement parts and labor, but there are some additional costs that could come up. From scheduling an inspection to diagnose the problem to hiring a pro for an emergency fix, here are some potential costs to consider.

Inspection

A furnace inspection costs about $80 to $100 on average. When the furnace stops blowing warm air or starts cycling inconsistently, it could be the control board—or it could be dozens of other parts that are worn out or broken. That’s why it’s important to have a furnace repair person perform an inspection when you suspect something is wrong. 

Maintenance

Keeping up with furnace maintenance, such as annual inspections and cleaning, will cost you about $120 to $500 per year but will save you in the long run. Dust and debris make it harder for the furnace to run efficiently, putting more stress on its parts. Over time, slacking on scheduling those furnace inspections and cleaning sessions or failing to change the furnace filters every few months can cost you more in repairs and higher utility bills.

Emergency Services

If a power surge causes the control board to stop working just as the temperatures outside drop below freezing, you’ll need to call in a furnace repair pro for emergency service. Emergency furnace repair costs about $90 to $230 per hour, plus the cost of parts.

Why You Should Hire a Furnace Repair Pro

While a DIYer with an understanding of HVAC systems and control boards might be able to get this project done for $50 to $300 by paying only the cost of a new circuit board and a screwdriver, experience is essential. Even confident DIYers still need to budget to have their furnace inspected by furnace repair pros located nearby for between $80 and $100 to make sure they aren't about to swap out a perfectly good circuit board due to incorrectly diagnosing the issue.

Here’s why it’s ideal to hire a furnace repair pro

Keep your safety in the forefront with these reasons to skip DIY on electrical work for your furnace:

• This project involves working on high-voltage components.

• There's a big risk of electrical shock if you mistakenly wire the wrong parts.

• While you may be familiar with circuit boards, furnace models can use a wide variety of control boards that require different calibrations.

• There's a chance you could find out the root cause of your problem wasn't the circuit board after you diagnose and replace a broken control panel on your own.

• An incorrect repair can cause the release of a clear, odorless, and deadly gas called carbon monoxide into your home.

If you want to DIY furnace control board repair

If you want to participate in the process, focus on shortening the amount of time a tech will spend diagnosing the issue by:

• Creating a clear access point to your furnace in your home.

• Shut the furnace off as soon as you notice error codes or a burning smell to prevent further damage.

• Writing down any error codes you see to help the pro make a faster diagnosis after arriving.

4 Tips to Save Money on Furnace Control Board Replacement Costs

This unexpected cost doesn’t have to break the bank. Fortunately, your furnace warranty may help cover the cost of parts, and by finding a trustworthy repair pro, you can save on this project. If you want to save even more on furnace control board replacement costs, be sure to:

• Check the warranty: A furnace typically includes a limited parts warranty of 5 years, or you may register for a 10-year warranty. The warranty may cover the cost of materials.

• Get multiple quotes: Compare HVAC quotes from at least three companies, and double-check reviews and references. Opt for the best value rather than the lowest rate.

• Consider universal parts: Universal parts tend to cost less than manufacturer parts. Check that the new control board is compatible with your type of furnace.

• Look for seasonal deals: New furnace parts may cost more in the busy winter season. If you know your control board is faulty, you may score a better deal by shopping early.
