Maytag Wall Oven MEW5530DDB, elements not getting fully red hot, elements continuity is good, replaced heating sensor, elements not getting RED hot as they use to be.
Check the voltage to the oven. Also, check the contacts on the oven relay. (If the relay shows signs of having been overheated, the contacts are probably bad, but not every bad contact will cause visible overheat damage.)
Inspect all of the connection terminals in the wiring from the inlet power to the controller relay to the heating elements. A poor connection will overheat the wire but prevent proper heating of the element. Heavily oxidized or loose terminals should either be cleaned up or replaced. Since you say both elements have the problem, I would start first with the input power connection. That includes turning off the breaker to the oven and checking the wall socket.
If you have aluminum wiring to the wall socket, the connection may need to be redone. First verify that the socket is marked for aluminum wiring (Al or Al/Cu). Aluminum wire connection requires great care: the wire must be cleaned to expose shiny metal, then immediately coated with a special grease made for aluminum wiring before insertion into the socket terminals, and the terminals must be torqued to specification. Otherwise, you will eventually have a poor connection and possible fire hazard. If you don't see any grease on aluminum wire, that could be the problem. If you have copper wire, standard wiring procedures apply.
