Frigidaire Cooktop Error Code E22

E22 on a Frigidaire cooktop means the control system has detected a defect in the timer key sensor, which is part of the touch control interface. The board cannot receive a valid signal from that sensor, so it triggers the error to prevent unsafe operation. The fault is typically located in the wiring connections or the touch control panel for the right front cook zone.

A power reset by turning off the circuit breaker for 30 to 60 seconds may temporarily clear the E22 code, but it will return if the underlying fault is not corrected. If the sensor or wiring connection is genuinely defective, the error will reappear as soon as the cooktop powers up and runs its diagnostic checks. A reset is useful for confirming whether the fault is intermittent or persistent.

Repair costs depend on the failed component. If only a wiring harness or connector needs replacement, parts and labor may range from around $75 to $150. A touch control panel assembly typically costs between $100 and $250 in parts, plus labor. Main control board replacement tends to be the most expensive option, often ranging from $150 to $350 or more for parts and professional installation.

Some causes of E22 are DIY-friendly, such as reseating a loose ribbon cable or cleaning contamination off the touch panel. Start by disconnecting power, then inspect and firmly reseat all cable connections between the touch panel and the main control board. If the error returns after these steps, the touch control assembly or control board may need professional replacement.

It is not recommended to operate the cooktop while E22 is active. The error indicates a sensor fault that the control board cannot resolve, and the cooktop may have already disabled one or more zones as a safety measure. Continuing to use it could mask a wiring issue that poses a risk of unintended operation or further component damage.
