M1 Notes; M2 Oven Control Testing Procedures - Maytag AGS1740BD series Service

Testing Procedures
To avoid risk of electrical shock, personal injury or death; disconnect power and gas to range before servicing,
unless testing requires power and/or gas.
M1 (AGS1740BD*, MGS5752BD*) NOTES:
1
"Action Taken" applies as long as the condition exists. If the condition goes away, the control recovers.
2
If there is a cook function or timer active, the function continues. The user cannot edit the function, and [Cancel] will cancel the cook
mode.
3
Flash rate: 0.2 seconds on, 0.1 second off. Pressing any key will clear the display until the fault clears and is re-triggered.
4
"Action Taken" applies until there is a POR (Power On Reset ["hard reset"]).
5
If the control believes the door is locked, it will attempt to unlock it when the function cancels and the cavity temperature cools.
6
Special conditions for latch faults (9dxx):
•
A known good unlock position is defined as when the unlock switch reads closed and lock switch reads open.
•
A known good lock position is defined as when the unlock switch reads open and lock switch reads closed.
•
A faulted switch means the switch input is reading an invalid state, neither open nor closed.
•
If at POR, the latch is not at a known good unlock position:
•
Affected DLBs (Double Line Breaks) and loads are disabled during detection.
•
If the control is in a known good unlock position and the lock switch becomes faulted:
•
The control will not fault.
•
If a function requiring latch movement is attempted while the lock switch is faulted, the control will sound an error
tone and the function will be disabled.
•
If the control is in a known good lock position and the unlock switch becomes faulted:
•
The control will not fault.
•
If a function requiring latch movement is attempted while the lock switch is faulted, the control will sound an error
tone and the function will be disabled.
