Customer Questions and Answers for Auxiliary Relay by Whirlpool

This auxiliary relay is an electrical switch used by the control to route line voltage to high-demand components. Replacing a weak or failed relay restores reliable power delivery for consistent heating and fan operation, depending on the model.

• Switches power to elements, fans, or other high-load components when signaled by the control
• Offloads high current from the electronic control for durability and reliability
• Common symptoms can include: oven not heating or heating intermittently; element or blower won't run; audible clicking with no heat; discoloration or melting at relay terminals
• Supports stable operation by providing a dedicated, serviceable switching point in the circuit

• Disconnect power at the breaker and verify no voltage before servicing
• Access the relay near the control/wiring harness; note its mounting orientation
• Move wires one at a time to matching terminals; ensure snug spade connections and repair any heat-damaged wiring
• Secure the relay, reassemble panels, restore power, and test operation
