What LOWER RELAY Means
On a legacy Dual Fuel range with a lower oven or storage-drawer heating function, this code means the control board has detected a problem with the relay controlling that lower section's power — similar in nature to the same-named problem on L-Series double ovens.
Common Causes of LOWER RELAY
- A failed or stuck relay controlling the lower section
- A wiring problem between the board and the lower heating circuit
- A control board problem reported through this relay
🔧 One Safe Check You Can Try
Confirm whether the main oven cavity still heats and holds temperature normally — that tells you whether the problem is isolated to the lower section or affects the whole control system.
⚠ Why You Shouldn't Go Further Than That
- A relay stuck closed can leave a heating circuit energized even when the display shows it off.
- The relay is on the same control board as other functions, so an incorrect repair can affect more than just the lower section.
- Testing a relay live is a shock risk best left to a technician.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
