5. If the RTD is on the heater element, remove
the RTD (512) to avoid damage. See
Replace RTD, page 60.
6. Use a wrench to remove the heater element
(508). Inspect element. It should be relatively
smooth and shiny. Replace element if there is a
crusted, burnt ash-like material adhered to the
element, or if the sheath shows pitting marks.
7. Install the new heater element (508), holding the
mixer (510) so it does not block the RTD port.

Repair Heater Overtemperature
Switch
1. Perform Shutdown, page 50.
2. Wait for heaters to cool.
3. Disconnect overtemperature switches (509) from
cable (88). Test across spade terminals with
ohmmeter.
a. If the resistance is not approximately 0 ohms,
the overtempe rature switch (509) needs to
be replaced. Go to step 5.
b. If the resistance i s approximately 0 ohms,
inspect cable (88) to ensure it is not cut or
open. Reconnect the overtemperature switch
(509) and cable (88). Disconnect cable from
theTCM.Testfrompin1to3and1to4.If
the resistance is not approximately 0, and
switches are 0, replace cable in place or
original cable.
4. If the switch fails the test, remove the screws.
Discard the failed s wi tc h. A pp ly a thi n layer of
thermal compound 110009, install a new switch
(509) in the same location on housing (501).
