GE Cooktop Error Code 174

Error code 174 on a GE cooktop indicates a display board BV supply failure, meaning the board has detected a problem with its own operating voltage supply. This can result from a temporary power disturbance or from an actual hardware failure within the display board. The cooktop logs this fault to prevent unsafe operation when control electronics are not functioning correctly.

Start by recycling power at the circuit breaker for 60 seconds to rule out a transient fault. Also check that all wiring harness connectors at the display board are fully seated and secure. If the error persists after those steps, the display board itself needs to be replaced, as it is the component reporting and experiencing the voltage supply failure.

If the fault clears with a power recycle, there is no parts cost involved. If the display board requires replacement, parts typically range from around 80 to 250 dollars depending on the cooktop model, with professional labor adding another 100 to 200 dollars in most cases. Obtaining the specific board part number from the cooktop model sticker will help narrow down the parts cost before committing to the repair.

A power recycle is always the first step and will clear the fault if it was caused by a temporary power fluctuation. Turn the cooktop off at the circuit breaker, wait at least 60 seconds, and restore power. If the 174 code returns after the reset, the display board has an internal failure and will need to be replaced.

It is not advisable to continue using the cooktop while this fault is active. A BV supply failure indicates the display board is not operating correctly, which means user input and burner control signals may not be processed reliably. Discontinue use until the fault is diagnosed and resolved to avoid unpredictable behavior.
