What C-A2 means on your Dacor range (dacor range c-a2)
Dacor range c-a2 means the main PBA has detected the cooling fan motor is not behaving as expected — running slower than commanded, not starting, or not stopping when it should. This is the same cooling fan referenced in the c-31 overheating discussion, but c-a2 is triggered by the motor’s own feedback rather than an elevated board temperature reading, so it can appear even before the board has actually overheated. Because the cooling fan protects the control electronics through both oven use and nearby cooktop heat, Dacor rates a confirmed motor failure Medium severity even when the range still appears to function normally in the short term.

Symptoms
Read these against your range: they are what tells C-A2 apart from the other things that can go wrong on a Dacor range.
- C-a2 appears while the range is running or shortly after a cycle ends.
- The cooling fan may be audibly silent, unusually loud, or running at an inconsistent speed.
- The fan may continue running long after a cook cycle has ended and the range has cooled.
- A faint burning-dust smell can appear the first time a struggling fan motor overheats slightly.
- The range may still bake and broil normally in the short term even with c-a2 present.
Common causes
What produces C-A2 on a Dacor range is not always the component people assume, which is why the range causes below run from most to least likely.
- Blocked or seized cooling fan motor — debris or bearing wear is preventing normal rotation.
- Failed fan motor — the motor itself has stopped responding to the main PBA’s commands.
- Damaged fan wiring — a chafed or loose wire interrupts power or feedback to the motor.
- Main PBA fan-control circuit failure — less commonly, the board’s own driver circuit for the fan has failed.
- Obstruction in the ventilation path — grease buildup near the cooktop can restrict the fan blade from turning freely.
Troubleshooting steps you can try
Work through these checks on your range in order before calling anyone out, and stop wherever mains voltage, gas, a hot surface or a sealed component on the range is involved.
- Listen closely near the rear of the range during and after a cycle to judge whether the fan sounds normal, weak, or absent.
- Power-cycle the range at the breaker and note whether the fan behavior changes on the next cycle.
- Avoid running long or high-heat cycles until c-a2 is resolved, since the board relies on the fan during those cycles most.
- Check that nothing is stored against the range’s ventilation openings that could restrict the fan.
- Do not attempt to access or clear the fan assembly yourself — it is inside the range housing.
Parts a technician may replace
Expect the cooling fan motor, fan wiring, and main pba to be checked on your Dacor range. Replacing more of a range than the problem requires is how a small range repair becomes an expensive one, so the failed part is confirmed first.
When to call a technician
A cooling fan that is not running correctly puts the control electronics at ongoing risk, so book a technician to inspect the motor and wiring rather than continuing to run long cycles. This rates Medium on a range, so take your time — but do not keep clearing C-A2 on the range without finding out why. Repairs to your range are carried out by independent technicians using genuine parts, with 30 days of labor cover.
