Merrychef High-Speed Oven Error Code E091: Recommission Turntable
E091 is a recommission test result for the turntable: no user input was registered. The manual lists it but marks it not applicable to the e2s, so on the e2s the code should not normally appear. On models with a turntable, check the turntable drive.

What does Merrychef error code E091 mean?
E091: Recommission Fail Turntable is one of the results the oven writes during the recommission test. The test asks the person at the oven to confirm what each part is doing, and this entry is made when no response is registered for the turntable step. The manual lists the code but marks it not applicable to the e2s, which has no turntable of its own, so the code only has a practical meaning on ovens built with a turntable. Its action is generic: check the turntable drive, which depends on the model. The applicability to the e3 rests on the shared recommission list, and the e3 manual itself was not opened. On a turntable oven the usual picture is a platter that does not turn, either because the motor is not driving it or because the coupling to the platter has slipped. The oven only reports that the response did not come.
