Quick answer
If your Wolf CT Electric Cooktop shows E50, the available reference information links it to heat-sink thermistor open. Confirm the exact model before using the code to make a repair decision.
Model compatibility: Wolf reuses codes across series and model years, so E50 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
heat-sink thermistor open
Signs
Symptoms you may notice
The message may return at the same point in a cycle if the monitored circuit remains out of range.
A related cooking mode may work differently from the rest of the appliance.
Temperature feedback may be missing, implausible, or inconsistent.
Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Perform one power reset if there are no safety concerns.
Do not bypass, short, or resistance-test internal sensors from live appliance wiring.
Record whether the code appears cold, during preheat, or only after the appliance reaches temperature.
Important safety warning. Safety first: stop using the appliance and disconnect power only if it can be done safely if you notice smoke, a burning smell, arcing, repeated breaker trips, abnormal heat, gas odor, or water near electrical parts. Internal electrical, gas, steam, and high-temperature diagnostics should be left to a qualified technician.
Please avoid
What not to attempt
Do not bypass a sensor, short probe terminals, or test internal circuits while the appliance is energized.

When to call a technician
A persistent E50 should be diagnosed with the exact model information. The sensor or probe, its wiring and connectors, and the control input all need to be tested before any part is replaced.
Seeing this code on your Wolf appliance?
Book a specialist visit for a clear estimate and approval before any repair. Independent service — not an official Wolf service center.
Code E50 points toward heat-sink thermistor open. The fault may be caused by the named component itself or by related wiring, connectors, power, installation conditions, or another part of the same monitored system.
You can try only the safe external checks listed above and one power reset when the appliance shows no signs of electrical damage, overheating, gas, or water near electrical parts. If E50 returns, do not keep resetting it; the appliance is still detecting the condition.
Not by itself. An error code identifies a system, circuit, state, or monitored condition. Wiring, connectors, power, installation conditions, sensors, loads, and controls can produce similar symptoms, so testing should come before parts replacement.
