Wolf Oven 1121 Error: Upper Right Conv Relay Open
What Does Wolf Oven Fault Code 1121 Mean? The 1121 fault code on a Wolf M Series wall oven is an upper right convection element relay open fault. M Series convection ovens use multiple convection elements to distribute heat uniformly across the cavity, and each element has its own dedicated relay on the upper relay […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
Yes. The 1121 fault does not create a safety hazard — it simply disables one convection element. Radiant bake, broil, and even partial convection (with reduced power) all remain usable. Schedule service at your convenience.
Can I reset the code?
Yes. Transient relay faults clear on breaker reset. Persistent 1121 after reset means the hardware has failed and needs replacement.
When to stop immediately?
Stop if you notice: 1121 returns on every convection attempt, Any burning smell from the upper cavity.
Symptoms You May Notice
Convection bake produces uneven results
With one of the convection elements not firing, airflow-baked food shows browning patterns uneven across the cavity — typically darker on one side than the other.
Convection cycle starts but takes much longer than normal
The remaining convection elements compensate, but total cook time extends noticeably because the oven can only deliver partial convection power.
Radiant bake mode works normally
Standard bake mode does not use the convection elements, so it operates without any change while 1121 is present.
Possible Causes
Upper right convection relay mechanical failure
The relay no longer closes when the coil is energized — worn contacts or a weak coil spring.
Requires ProfessionalOpen upper right convection element
The element itself has failed open from thermal cycling and no current flows even with the relay working.
Requires ProfessionalRelay driver fault on upper relay board
The driver circuit that energizes this specific relay coil has failed.
Requires ProfessionalSafe Checks You Can Do
-
1
Reset power at the breaker
Switch off the dedicated wall oven breaker for 60 seconds, then restore power and run a short convection test at 350°F.
Transient convection relay faults from power glitches often clear on a single reset.
-
2
Switch to radiant bake mode
Continue using the oven in radiant bake mode (not convection) until service arrives. Radiant bake does not depend on the failed relay path.
Watch for any uneven browning during convection to confirm one element is clearly not firing.
When to Call a Professional
Contact a qualified technician if:
- Uneven convection browning on multiple bake cycles
- Convection element visibly discolored or damaged
- First fault on an otherwise healthy oven
