Potentiometer Removal And Replacement - Thermador Pro Grand Next Generation PRD48JDSGC/02 Service Manual

Service Manual for the Thermador Pro Grand Next Generation, Dual Fuel Range with Steam Oven, Models: PRD48JDSGC/02, PRD48JDSGU/02
Gas Leaks
With electrical power off, carefully check for gas leaks at each gas
component that was removed, replaced, or otherwise serviced using a
gas leak detector (electronic leak detectors are highly recommended)
or bubble test. For XLO valves, you may need the electrical power to
be on when testing for gas leaks. Use extreme caution when
performing gas leak testing on XLO valves with electrical power on.

Potentiometer Removal and Replacement

The potentiometer (also known as the simmer control
potentiometer ) is used for simmer (XLO) and also XHi functionality. It
is accessible from under the maintop and also requires control panel
removal. It should not be confused with the oven function/temperature
selector switch, which is also a type of potentiometer.
Be sure to check QuickFinder for relevant information, documentation,
and the correct part number when replacing this component.
1. Follow all safety precautions and steps in Preparing the Range for
Servicing, page 25.

2. Follow all steps in Accessing Components under the Maintop,
page 25.
3. Remove the control panel (see Control Panel Removal and
Replacement, page 35).
4. Detach the white side connector from the potentiometer by
pressing on the tab, and pulling it off.
5. Rotate the valve shaft until you can slide the potentiometer off of
the valve shaft (see Figure 140).
6. Replace the potentiometer if needed.
Gas Leaks
With electrical power off, carefully check for gas leaks at each gas
component that was removed, replaced, or otherwise serviced using a
gas leak detector (electronic leak detectors are highly recommended)
or bubble test. If potentiometer servicing involved removing an XLO
valve, you may need the electrical power to be on when testing for
gas leaks. Use extreme caution when performing gas leak testing on
XLO valves with the electrical power on.
