A15633102: Is This the Only Number You Need to Match?
The sticker on this board carries the full production number, A15633102, start to finish. Numbers printed on the green board itself are component codes, not the part number.
No service number exists for this board, so there is no older design it replaces or consolidates. If a replacement arrives with a different connector layout or mounting pattern than the one you removed, stop before installing it. Compare size, connector layout and mounting points first, then send us both photos: the board that came out with all of its stickers, and the one that arrived.
This is not a universal main control board - it is a direct replacement for the part number printed on your original board. Boards that look identical can be programmed differently, so always match the number on the sticker.
Which Frigidaire Refrigerators Use the A15633102?
No models are confirmed for this board, so the sticker on your old board is what decides. Compare it to A15633102 character by character.
On this refrigerator the board is mounted either on the back panel or behind an access cover inside the cabinet, commonly behind the lower front grille near the freezer drawer. This model list is for reference only. Frigidaire may change boards between production runs, so two refrigerators with the same model number can use different boards. Always order by the part number printed on your original board - it is the only identifier that decides.
Opened or installed boards may carry a restocking and retesting fee, so compare the sticker before you open the anti-static bag. Hold yours next to A15633102 and check it character by character.
Frigidaire Refrigerator Not Cooling? Is It the A15633102 or Something Else?
These checks help you rule out the common causes before you order. Only a qualified technician on site can confirm the fault in your refrigerator. Unplug the refrigerator before you take any panel off, and stop at any step you are not comfortable with.
Some models show an error code on the display, but since no code list is confirmed for this board, diagnose by symptom instead.
Let's verify it is the board by checking the common parts that contribute to these failures. They are inexpensive, easy to check, and ruling them out means you order once, with confidence.
Confirm the number on your sticker
Read it before you open anything else. If it matches A15633102 character by character, this is your board.
Check power at the outlet and breaker
Confirm the outlet is live and the breaker has not tripped. A dead outlet looks exactly like a dead board.
Test the temperature sensors
When a sensor shorts or opens, the board makes a bad decision on bad information, and that is not the board's fault. Compare each reading against the tech sheet, the wiring and test chart packed inside the appliance.
Defrost heater and thermal fuse
Both should show continuity. A back wall packed with frost on a good board usually points to one of these parts, not the control.
Fans and start relay
Both the evaporator and condenser fan should spin freely by hand. A struggling start relay or overload puts a load on the board driving it.
Once the power, the sticker match, the sensors, the defrost parts and the fans all check out, the board is what is left. You need a replacement main control board, and this time you order it once and get it right. A fan or sensor that has been failing quietly for weeks can stress the board driving it long before the board itself gives out. Keep a spare on the shelf and a warm fridge becomes a short repair instead of days without cooling.
How Do You Replace the A15633102 Frigidaire Refrigerator Main Control Board?
Repair times and difficulty levels are general estimates and may vary by model, tool availability, and experience. This is provided as general guidance only and is not a substitute for professional service. Food is normally fine during a typical install, but we highly recommend moving it to a cooler with ice as a precaution - Appliance Pro USA is not responsible for lost or spoiled food.
Disconnect power at the wall before you touch anything inside the cabinet.
Pull the drawer out and detach the grille to reach the control board housing.
Pry the housing down and forward to free it from the cabinet.
Shoot each harness and its orientation before disconnecting anything. This is your map for reassembly.
Some models hold the board with a test-port plug and a retaining tab. Release both before lifting the board clear.
Match every harness to your photo, replace the test port plug, then refit the grille and drawer.
- ✓I photographed my board sticker and read every character
- ✓I confirmed the outlet is live and the breaker has not tripped
- ✓I checked the temperature sensors against the tech sheet
- ✓The defrost heater and thermal fuse both pass continuity
- ✓Both fans spin freely and the start relay checks out
On this board it goes in as a straight swap. We have not seen a programming step tied to a standard replacement. Let the unit run for a few hours at its normal setting before deciding if it is cooling correctly. The 5-mil nitrile gloves in the box give grip and some protection, but they are not cut-proof. Hold the board by its edges and mind the sheet-metal edges of the cover.
Still Not Cooling After You Installed the A15633102?
Clicks and relay sounds are normal. The compressor may stay off for several minutes as a protection delay.
Fans run, compressor hums, and cold air shows up in the freezer first.
Both sections reach near set temperature. Do not load warm groceries before this.
Temperatures stabilize and the ice maker resumes. Now decide whether anything is wrong.
Once power is back on, the board compartment is live. Do not reach into it or reseat a plug with the refrigerator plugged in. Unplug first, every time.
Compare the new board to your photo
Connector layout and mounting points should match the board you removed. If they do not match, stop and compare stickers before you reinstall.
Reseat every harness
A connector pushed in at an angle can look seated but still read as a dead board. Press each one straight in until it clicks.
Recheck the sensors
A sensor that was marginal before still feeds the new board the same bad reading. Go back to the tech sheet and recheck each one.
Confirm the test port plug is back in place
Some models will not run correctly with the test port open. Make sure it is seated before you close the grille.
Still stuck? Talk to us before you return anything
Let the fridge run for a few hours at its normal setting, then message us with the symptom. Troubleshooting is free.
The troubleshooting steps above are general guidance only and may not apply to every model or situation. If you are unable to resolve the issue after following these steps, we recommend contacting our team or consulting a qualified appliance technician before taking further action.
How Do You Help Your New A15633102 Control Board Last?
Surge protection
A power outage or utility spike sends voltage straight through the board. Repeated short outages wear on it as much as one long one.
Clean the condenser coil
A dusty coil makes the compressor and fans run longer and hotter, and the board runs hot right along with them.
Check for moisture near the housing
A blocked drain or a weeping water line can put moisture into the control board housing. Wipe the area dry and look for staining before you close it up.
What Else Is Worth Checking While the Fridge Is Open?
Temperature sensors Do it now
Inexpensive and already exposed once the housing is off. A sensor near the end of its life can make a good board look faulty.
Defrost heater and thermal fuse On frost
Already in reach once the rear panel is open. Getting back in later means emptying the freezer again.
Start relay and overload On clicking
A struggling relay drags on the board driving it. A quick check while the panel is open costs a couple of minutes.
Evaporator and condenser fans If a blade drags
A fan with a worn bearing runs hot and loads the board. Replace it now if either one rumbles.

Warranty coverage is determined at Appliance Pro USA's discretion. Boards that have been tampered with, or with our verification stickers or holograms removed or damaged, are not eligible for warranty coverage. Any board that has been flashed, reprogrammed, or had its firmware altered is not eligible for return or warranty coverage. Opened or installed boards may carry a restocking and retesting fee, so compare the sticker before you open the anti-static bag. Minor cosmetic wear may be present due to prior installation - it does not affect performance.
What Else Do People Ask About the A15633102?
Why does searching A15633102 bring up so few results?
No separate service number exists for this board on record, so A15633102 is the only number to search or order by. Match it character by character against your sticker to confirm fit.
What ships in the box with the A15633102?
The board sealed in an anti-static bag, the Quick Start Guide, a pair of install gloves, and the warranty registration card.
The board I received does not match the one I removed. Is it wrong?
Stop before installing it. Compare size, connector layout and mounting points against the board you removed. Send us a photo of the board you removed with all of its stickers and a photo of the one that arrived, and we will confirm before you go further.
I ordered the wrong board. What now?
Leave the bag sealed and contact us first. An exchange is the fastest path. Opened or installed boards may carry a restocking fee.
Does the A15633102 need programming or setup after I install it?
On this board it goes in as a straight swap. Let the refrigerator run several hours at its normal setting before deciding if it is cooling correctly. Any board that has been flashed, reprogrammed, or had its firmware altered is not eligible for return or warranty coverage.
Is the A15633102 discontinued?
No. The A15633102 is not discontinued by the manufacturer as of this writing, so it ships as a new board rather than a used part.
My Frigidaire refrigerator is completely dead. Is it the board?
Check the outlet and the breaker first. If the outlet is live and nothing inside responds, the board is a strong candidate, and the checks above take only a few minutes.
