KitchenAid Ice Maker E5 Error: Timed Ice Making / Heater Bimetal
What Does KitchenAid Ice Maker Error Code E5 Mean? E5 on a KitchenAid stand-alone ice maker is documented as Timed Ice Making or Heater Bimetal fault. The control board times each production cycle and expects it to complete within a specified window. Cycles that run longer than the timeout trigger E5 — often because cooling […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
Maybe. If condenser cleaning resolves E5, the unit is safe to use. A persistent fault after cleaning indicates a deeper issue requiring service.
Can I reset the code?
Yes. Clean-condenser E5 clears when production returns to normal timing. Sealed-system or heater-bimetal faults do not clear with reset.
When to stop immediately?
Stop if you notice: E5 returns after a thorough condenser cleaning, Production rate below half of specification.
Symptoms You May Notice
Very slow ice production before E5 latched
Recent batches took much longer than normal before the fault appeared — a gradual decline in production rate that eventually exceeded the timeout threshold.
Production halted with E5 displayed
The control panel shows E5 and no new ice is being produced. The cabinet may still be cold but the harvest mechanism is idle.
Harvest heater not responding to test
During diagnostic mode, the heater test produces no warmth because the thermal bimetal protecting the heater has opened and broken the circuit.
Possible Causes
Harvest heater bimetal opened from overtemperature
The bimetal thermal limiter on the harvest heater has opened due to repeated overheating, usually caused by insufficient water in the mold or an upstream fault.
Requires ProfessionalCabinet cooling degraded
The sealed system is underperforming, causing each production cycle to take longer than normal. Eventually the cycle time exceeds the board timeout threshold and E5 is set.
Requires ProfessionalCondenser coil fouled reducing cooling capacity
A dust-blocked condenser coil forces the compressor to work harder and each production cycle runs longer than it should. Condenser cleaning can resolve this.
DIY PossibleSafe Checks You Can Do
-
1
Clean the condenser coil thoroughly
Unplug the ice maker. Remove the front grille and vacuum the condenser coil with a brush attachment. Clean any dust and lint buildup. Reinstall the grille and restore power.
A visibly dusty condenser is often the root cause of gradually lengthening production times that eventually trigger E5.

Give the unit 4 hours after cleaning
After condenser cleaning, let the ice maker run for 4 hours and monitor whether production returns to normal speed. If the unit completes multiple production cycles without re-tripping E5, the coil cleaning resolved the issue.
Production rates should return to the manufacturer specification (roughly 50 lb per 24 hours on most stand-alone models) within the first day after a coil cleaning.
When to Call a Professional
Contact a qualified technician if:
- Harvest heater replacement clears the fault
- Sealed system performance measurably degraded
- Compressor not reaching specification run current
