netic reed) have
issues. The oven can continue to
cook but cleaning cycle
could not be performed
until the drawer will be in
place; Ensure that the
cleaning drawer is in its
housing and inserted
properly in order to trig-

- Oven installed
by hot machines.
- Steam/Heat
leakage in the
electronic
compartment.
- SSR internal
issue.
Do not switch the oven

ature to decrease. Clean
the air inlet filter. Check
with a thin strip of paper
whether a consistent air
flow can be detected at
the cooling air inlet.
Check if the inlet cooling
air may be affected by
heat produced in the
kitchen (in case the oven
is located by hot units,
stop working with those
units).
If the error persists call
Service.
Activates at 85 ℃ /Reset at 75 ℃ .
Check room temperature consid-
ering the oven needs fresh air to
cool electronic compartment.
Clean the air intake filter. Check
inner lack of cavity insulation/
other heat transmissions from
cavity to SSR. If needed fix it.
Verify heat sink integrity.
