What the E37 error code actually means

The E37 code means your Frigidaire induction cooktop has detected a problem with the temperature monitoring system inside the module that controls the left side burners. The cooktop shuts down this function to protect itself from overheating since it can no longer accurately measure the heat levels inside that module. A technician will most likely need to replace the circuit board that controls the left side cooking zones to resolve this error.

Questions people ask about E37

What does E37 mean on a Frigidaire cooktop?
E37 indicates a heat sink temperature sensor break in the 3-zone induction module that controls the left-side cooking zones. The cooktop has detected an open circuit in the sensor that monitors temperatures inside the left front and left rear induction generator board. This is a protective fault that disables operation to prevent potential overheating of the module's electronics.
Is it safe to use my Frigidaire cooktop when E37 is displayed?
No, you should not continue using the cooktop while E37 is active. The error means the system can no longer monitor heat sink temperatures in the left-side induction module, removing a key safety protection against overheating. Operating the unit without functional thermal monitoring could allow the electronics to overheat, potentially causing further component damage or creating a fire risk.
How much does it cost to repair an E37 error on a Frigidaire cooktop?
Repair costs will vary depending on parts availability and local labor rates, but you can generally expect to pay somewhere in the range of $150 to $400 or more for a generator circuit board replacement when including both parts and professional labor. Getting a service estimate before committing to the repair is advisable, especially on older units where repair cost versus replacement cost should be weighed.
Can I fix the E37 error myself on a Frigidaire induction cooktop?
The primary repair is replacement of the LF/LR generator circuit board in the 3-zone induction module, which requires disassembling the cooktop and working with high-voltage power electronics. A preliminary check of wiring harness connectors is something a knowledgeable DIYer can attempt, but the board replacement itself is best handled by a qualified appliance technician due to the voltages involved in induction cooking systems.
Will resetting the cooktop clear the E37 error code?
A power reset by disconnecting the cooktop from its power source for several minutes may temporarily clear the error display, but the code will return if the underlying sensor circuit fault is still present. E37 reflects a hardware fault, specifically an open sensor circuit, so it requires a physical repair rather than just a reset to permanently resolve.
