Cavity 1 / Cavity 2 meat probe
error
“Hot” wire shorted to ground. Connection to
the probe changes from connected to
disconnected multiple times. Probe is disabled,
but oven continues to operate. Error will be
cleared and probe enabled after a control
reset. Standard probe assembly is part of the
control module; see Communication Schematic
Check wires and connections; connector may be loose
and shorted to cavity or other dead metal.
Check for dirty contact within probe receptacle.

E222
Cavity 1 / Cavity 2 meat probe
sensor temperature too high
Meat probe or receptacle failure. Measured
temperature of probe is higher than allowable
limit. Oven will stop heating until probe is
Check with customer to determine if probe was in
receptacle and not in food.
Check probe operation and resistance.
Check for loose connections and/or pinched wires.

E223
Cavity 1 / Cavity 2 meat probe
sensor temperature too low
Meat probe or receptacle failure. Measured
temperature of probe is lower than allowable
limit. Oven will stop heating until probe is
Check with customer to determine if probe was used in

Cavity 1 / Cavity 2 door latch error
Switch signals lost by latch position switch.
If a locked or unlocked signal error occurs, all
heating elements will be disabled. Error may
be cleared only by a software reset. See Cavity
1 (upper) Small Load Schematic.
Check switch connections.
Check wires between connector and control module.
Check switch operation.
E303
Electronics Delta temperature too
high
Temperature sensor on the control module
detects temperature changes that, over time,
are higher than limit value. Control turns off
heating elements and fan defaults to high
speed. When cavity temperature reaches
212°F/100°C, heating will resume and error
will be cleared. (If self-clean was running, it will
be disabled until a control reset is performed.)
Check connections to cooling fan and to control
module (see Small Load Schematic).
Check element operation.
Check for air obstruction or damaged upper/lower
ventilation trims.
Check for stuck relays.
