Removing and Installing the Catalytic Converter
1. Unplug the oven.
2. Remove the IR element. (See above procedure.)
3. Once the IR element has been removed, remove
the catalytic converter clip (Item 121) to access
the catalytic converter. Figure 39.
NOTE
: It may be necessary to remove the
blower motor assembly (see page 48) to get
access to the top of the catalytic converter.
This will allow the catalytic converter to be
pushed down out of the housing. Figure 39.
4. Remove the catalytic converter (Item 122).
5. Inspect the condition of the catalytic converter
and either clean it or install a new one.
CAUTION: Clean catalytic converter using
only TurboChef cleaner (P/N 103180 USA,
103380 Intl). Use of other chemicals will
irreparably damage catalyst.
Installing a New IR Element
1. Unplug the oven.
2. Gently squeeze the new IR element together in
order to get the terminals and lead wires into the
cavity and through the mounting holes.
CAUTION: Do not allow the thermocouple
lead wires to kink. They are solid wire and
will break.
3. Once the IR element is installed, expand the IR
element in order to reinstall the shim washers
(Item 117) and snap rings (Item 116). Figure 39.
NOTE
: Be sure that the snap rings sit in the
grooves on IR element.
4. Reconnect the IR element lead wires to the EMI
filter and the high-limit thermostat.
5. Reconnect the IR thermocouple lead wires
to the thermocouple extension wires – Yellow to
Yellow and Red to Red.
