Dacor Oven E2 Error: Cooling fan fault
This dacor oven e2 error code guide explains what this fault means for your Dacor appliance and how to respond safely. What E2 Means on a Dacor Oven E2 indicates the cooling fan is not running at the speed the control board expects. Dacor Heritage and Modernist wall ovens rely on an internal cooling fan […]

Answer to continue safely
Is it safe to keep using?
No. Operating without a cooling fan risks overheating the control board and surrounding cabinetry.
Can I reset the code?
Yes. A breaker reset may clear E2 temporarily, but if the fan does not spin, the motor requires replacement.
When to stop immediately?
Stop if you notice: Do not use the oven until the cooling fan is confirmed operational — overheating the control board will cause a second, more expensive failure., Stop immediately if you smell burning plastic or notice the control panel acting erratically — the board may already be heat-damaged..
Symptoms You May Notice
Oven runs hotter than normal on exterior
The top and side panels of the wall oven feel significantly hotter than usual during and after cooking — heat that the cooling fan would normally exhaust is building up inside the chassis.
E2 displays during or after a cooking cycle
The fault code appears mid-cycle or immediately after the oven finishes cooking, when the fan would normally run its post-cook cooling cycle.
Fan noise stops prematurely
The cooling fan is normally audible for 15-30 minutes after the oven is turned off. When E2 is present, the fan either makes no sound at all, runs for only a few seconds, or makes a grinding noise.
Control panel display dims or resets
Excessive heat buildup inside the chassis from a failed cooling fan can cause the control board to throttle or reset as a secondary thermal protection response.
Possible Causes
Failed cooling fan motor
The brushless motor driving the cooling fan has seized or failed, preventing the fan blades from spinning. This is the most common cause and is specific to Dacor built-in wall ovens where the fan runs inside the sealed chassis.
Requires ProfessionalFan blade obstruction
A piece of debris, a fallen wire, or accumulated grease on the fan blades is physically preventing the fan from spinning to its rated speed, triggering the fault.
DIY PossibleFan speed sensor or control board output failure
The tachometer signal from the fan motor or the board output circuit that powers the fan has failed, causing the board to detect a fan fault even when the fan is mechanically intact.
Requires ProfessionalSafe Checks You Can Do
-
1
Listen for fan operation
Turn on the oven and listen for the cooling fan immediately — it should start within 30 seconds of the oven being switched on. Also listen for 15 minutes after the oven is turned off. No sound, or a grinding sound, confirms a fan problem.
The fan is louder at the top rear of the oven cabinet cutout — listen there.

2
Power cycle the oven
Turn off the circuit breaker for 5 minutes. Restore power and check whether the cooling fan starts. A transient board fault can occasionally cause E2 without the fan actually failing — confirm with a post-reset cook cycle.
If E2 returns within one cook cycle after the reset, the fan motor or wiring requires physical inspection.
When to Call a Professional
Contact a qualified technician if:
- Fan motor does not spin when power is applied directly — motor replacement required inside the oven chassis.
- Fan spins freely by hand but does not run under power — wiring or board output circuit failure.
- New fan motor installed but E2 persists — board fan-speed monitoring circuit has failed.
