Manifold For Rangetop Burners - Removal And Replacement - Thermador PRL304EG Service Manual

Service Manual for Thermador Pro Grand LP Gas Ranges, Models: PRL304EG, PRL364EDG, PRL364ELG, PRL366EG, PRL484ECG, PRL486EDG, PRL486EDPG, PRL484ELG
10. Remove the white plastic side connector from the potentiometer
by pressing on the connector's tab. (see Figure 86).
11. Detach the XLO valve from the potentiometer by using a small
flat-blade screwdriver to remove the XLO valve from the
potentiometer standoffs. Then slide the potentiometer off the valve
stem (see Figure 87).
12. 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 or bubble test. If potentiometer was accessed by
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 turned on.
4.5.8 Manifold for Rangetop Burners – Removal and
Replacement
Although range components can usually be accessed and replaced
without removing the manifold, this procedure is provided if the
manifold for the maintop burners needs to be replaced, for example, if
damage is sustained due to a gas leak in the manifold, or if the
threading on the manifold is bad due to removing the regulator.
NOTE: The manifold (for rangetop burners) is sold as an assembly,
which comes with XLO and standard valves pre-installed.
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 21.
2. Follow all steps in Accessing Components under the Maintop,
page 21.

3. Remove burner support rails (with jet holder assemblies attached)
by following the steps in Removing the Burner Support Rail,
page 24.
4. Remove the regulator from the manifold (see Regulator Removal
and Replacement, page 55).
5. Remove all knobs from their valve stems by slowly pulling knobs
straight out, away from control panel.
6. At each of the locations shown in Figure 132 on page 70, remove
and retain two screws inside each bezel (see Figure 89) to detach
the manifold support brackets at the back of the control panel (see
Figure 90 on page 49).

7. Detach all wire connectors to the LED indicators and temperature
gauge, and make a note of how all the wires are connected.
NOTE: It is always recommended to label and tag all wires, wire
connectors and harnesses prior to disconnecting them, so as to
correctly identify their connections/locations when re-assembling.
Alternatively, you can photograph the wire connections prior to
disconnecting (for example, with your mobile phone).
8. Remove the control panel (see Control Panel and Bullnose
Removal and Replacement, page 69).
