Appliance Control Board Replacement Cost
Where These Numbers Come From
- Source. Completed Bozmanfix jobs, January 2023 to October 2026: 69,165 jobs in our service records across Florida, Georgia, Texas, North Carolina, Pennsylvania and South Carolina. Nothing here is modelled or surveyed.
- What counts. Repairs where a control board was actually fitted, not visits that ended at diagnosis.
- What the figure includes. Part, labor and the service call as one total, which is what you actually pay.
- How to read it. Each row gives the median, then the middle half of jobs (the 25th to 75th percentile), then the number of repairs behind it.
Control Board Prices by Appliance
| Appliance | Board replacement, median | Middle half | Repairs | All repairs on this appliance |
|---|---|---|---|---|
| Refrigerator | $533 | $429 to $650 | 78 | $395 |
| Dryer | $507 | $395 to $640 | 21 | $355 |
| Freezer | $500 | $408 to $650 | 55 | $385 |
| Ice maker | $488 | $398 to $713 | 32 | $417 |
| Washer | $474 | $411 to $577 | 76 | $373 |
| Oven or range | $454 | $400 to $526 | 62 | $385 |
| Dishwasher | $410 | $341 to $448 | 36 | $340 |
| Any appliance | $460 | $393 to $566 | 572 | n/a |
Every figure is the whole invoice: part, labor and the service call together. The last column is the median of all repairs with a part fitted on that appliance, for comparison.
Two things stand out. First, the control board is above the typical repair on every single appliance in the table. A refrigerator board at $533 compares with $395 for all refrigerator repairs across 6,873 jobs, and a washer board at $474 compares with $373 across 5,214 washer repairs. A board is one of the dearer repairs you can be quoted, so it deserves a confirmed diagnosis before you approve it.
Second, the spread between appliances is real but not dramatic. The dishwasher board is the least expensive at $410, the refrigerator board the most expensive at $533. Two rows rest on small samples and should be read as indicative: the dryer, with 21 board jobs, and the ice maker, with 32 jobs and the widest middle half on the page, $398 to $713. Every other component is priced the same way on our appliance repair cost by part page.
What a Control Board Actually Does
A control board is the decision layer of a modern appliance. It reads inputs, such as temperature sensors, door switches, water level and the buttons you press, and it switches outputs: motors, heaters, valves, fans and on a refrigerator the compressor. When a board fails, the components it commands are usually healthy and simply never receive power.
Most appliances have more than one board, and they fail differently. The main control board runs the cycle and carries the relays that power the heavy loads. The user interface board sits behind the display and keypad. Many refrigerators and washers also carry a separate inverter or motor control board that drives a variable speed compressor or motor. Naming the wrong one is how a repair gets quoted twice, so the technician identifies which board has failed rather than which board is cheapest to try.
The Faults That Look Like a Bad Board
A blank display or a cycle that stops dead points everybody at the board. In our experience it is the conclusion people reach online most often and the one most worth checking, because several cheaper faults produce exactly the same picture.
No power reaching the board. A tripped breaker, a failed outlet or a damaged power cord leaves the appliance looking electronically dead with a perfectly good board inside it.
A failed sensor feeding wrong readings. The board acts on what it is told. A refrigerator temperature sensor that reads wrong makes the board stop cooling on purpose. That repair runs a median of $376 ($327 to $444) across 138 refrigerator jobs, well below the board.
A door switch or lock. If the board believes the door is open, it will not start the cycle. On a washer the door lock repair runs a median of $359 ($300 to $423) across 158 jobs.
A loose or corroded connector. Wiring harnesses vibrate loose on washers and corrode in humid laundry rooms. The board works; the signal never arrives.
A display or keypad fault. Buttons that do not respond can be the user interface board alone, which is a different part from the main board behind it.
None of these are distinguishable from outside the appliance. That is why a board quote without testing is a guess, and why our technicians test before naming the part. The general approach is described in how technicians diagnose appliances, and the error codes that often accompany board faults on washers are explained in washing machine error codes.
How a Technician Confirms the Board
The test is a process of elimination, and the order matters because each step rules out a cheaper repair before the expensive one is considered.
First the technician confirms the board is receiving supply power. Then the inputs are checked: are the sensors and switches reporting what is really happening in the appliance? Only when the board is powered and correctly informed, yet still fails to power the part it should be running, is the board itself named as the fault.
The last step is the one people skip. When a relay on a board burns, it is often because the load it was driving had shorted or seized: a motor dragging, a heater drawing too much, a valve coil failing. Fitting a new board onto the same faulty load destroys the new board. The technician therefore tests the component downstream of the failed relay before quoting, so the repair is done once.
Why the Board Price Varies by Appliance
The part is a different object on each appliance, and so is the labor to reach it.
Refrigerators and freezers sit at the top of the table, at $533 and $500. Their boards often manage defrost timing, fans, dampers and, on many current models, a variable speed compressor, so the part itself is more involved. See our refrigerator repair cost page for how the board compares with every other refrigerator fault.
Dryers and ice makers follow, at $507 and $488, though both rows rest on smaller samples. Washers come in at $474. Front loaders in particular carry a motor control board as well as a main board, and the two are not interchangeable; our washing machine repair cost page sets the board against the other washer repairs.
Ovens and ranges run $454, with the tightest middle half on the page, $400 to $526. The board sits close to the heat of the oven, and the job is fairly predictable once access is gained. Dishwashers are the least expensive at $410, partly because the board is usually reached from the door without moving the machine far.
What Brand Data Shows About Boards
Across 18,670 brand matched repairs, the share of washer calls that turned out to be a control board differs by brand. Control boards are 5.5% of GE washer calls in our records, against 1.5% for Samsung washers. The full breakdown is on what breaks by brand.
A share is the mix of failures inside a brand, never a reliability ranking. It tells a technician which part to suspect first on a given machine; it says nothing about which brand you should buy. The price of the repair, once the board is confirmed, depends on the appliance and the board, not on the badge.
What the Price Includes
Every figure on this page is one number covering the visit, the diagnosis, the board and the labor to fit it. The $99 diagnostic visit is applied to the repair when you approve it, so you do not pay for the diagnosis twice. The work carries a 90-day parts and labor warranty, and you can read what that covers on our appliance repair warranty page.

When a Board Replacement Is Worth It
A control board is usually a good repair, because it is a single part with a known price and the rest of the appliance tends to be unaffected by its failure. The decision changes in a few situations.
The board is one of two major faults. If the technician finds the board failed because a motor or compressor is failing too, the two quotes belong together, and that is the moment to compare the total with the price of a comparable new unit.
The appliance is near the end of its expected life. Age changes the arithmetic more than price does. Our lifespan guides, such as how long refrigerators last, cover the typical range for each appliance.
It is a refrigerator and the compressor is in question. A refrigerator board at $533 and a compressor at $846 ($482 to $1,237, 72 jobs) are very different decisions. Samsung and LG cover their inverter and linear compressors for 10 years of parts, so check the warranty before paying for a compressor.
The broader framework, appliance by appliance, is on our repair or replace guide. Our technicians give you the number and the reasoning on site, and if replacement is the better call they say so rather than quoting the board anyway.

Common Questions
How much does an appliance control board replacement cost?
A median of $460 across 572 completed Bozmanfix repairs, with the middle half of jobs between $393 and $566. That covers the board, the labor and the service call together. By appliance, the median runs from $410 on a dishwasher to $533 on a refrigerator.
Which appliance has the most expensive control board repair?
In our records the refrigerator, at a median of $533 across 78 jobs. The dryer follows at $507 across 21 jobs and the freezer at $500 across 55 jobs. The dishwasher is the least expensive at $410 across 36 jobs.
How do I know it is the control board and not something else?
From the outside you usually cannot. A failed sensor, a door switch, a loose connector or a power supply problem produces the same dead display or stalled cycle. A technician names the board only after confirming it receives power and correct sensor readings but does not power the part it controls.
Is it worth replacing a control board?
Usually yes when the rest of the appliance is sound, because a board is a single part with a known price. Compare the quote with the price of a comparable new unit and ask whether anything else is failing. On a refrigerator, a board at $533 is a very different decision from a compressor at $846.
Why did my control board fail?
Boards rarely fail on their own. A shorted motor, heater or valve can burn the relay that drives it, and moisture or a power event can damage the circuitry. If that cause is not found, the new board can fail the same way, which is why the technician tests the load as well as the board.
Do some brands need control boards more often?
The mix of repairs differs inside each brand. Control boards are 5.5% of GE washer calls in our records against 1.5% for Samsung washers. That is the share of failures within each brand, not a reliability ranking, and the repair price depends on the appliance rather than the badge.
Display dead or cycle stuck?
A technician confirms the board before quoting it, because cheaper parts produce the same symptoms. The $99 diagnostic visit is applied to the repair when you approve it.
