Replacing The High-Limit Probe; Replacing The Float Switch - Welbilt Frymaster FilterQuick easyTouch FQG120T Service Manual

1.15.5 Replacing the High Limit Probe
1. Drain the cooking oil from the frypot. Allow the frypot to
cool completely before proceeding.
2. Perform steps 1 through 8 from section 1.15.1.
3. Remove the bezel removing the two (2) screws on the
bottom of the bezel (see Figure 5 from section 1.15.4).
4. Locate the high-limit probe to be replaced inside the frypot
(see Figure 4).
5. Using pliers, carefully bend the outer tab at the rear of the
high limit until the high limit can slide back and out of the
retaining bracket (see Figure 9).
6. Removal of other components and/or repositioning the fryer
may be necessary to gain access to the bottom of the probe.
Remove the side access panel if applicable.
7. Carefully loosen and completely unscrew the compression
nut, then the pass-through nut on the frypot bottom (see
Figure 10).
8. Carefully remove and pull the high-limit capillary tube and
bulb through the bottom of the frypot (see Figure 11).
9. Remove two screws securing the high-limit mounting-
bracket (see Figure 12).
10. Mark and disconnect the wires from the high limit in the
control box (see Figure 13).
11. Remove the high limit from fryer by pulling the capillary tube and bulb through the control box opening.
12. Reverse the steps above for the high limit installation. Ensure that Loctite™ PST 567 or equivalent sealant is
applied to the threads of the replacement and screw it securely into the frypot. IMPORTANT: When installing
new high limit, ensure the capillary tube and bulb are positioned properly with tab back in alignment
prior to tightening the compression nut. Once tightened, the capillary tube cannot be repositioned.
13. Once the fryer is filled with oil check for leaks and proper operation.

1.15.6 Replacing the Float Switch.

1. Drain the cooking oil from the frypot. Allow the frypot to cool
completely before proceeding.
2. Disconnect the fryer from the electrical power supply.
3. Mark the position of the float switch in the frypot (see Figure 4
on the previous page). Ensure when removing the float switch
that its position is clearly marked and replaced properly.
Installing the float upside down will change the switch from N/O
to N/C. This could allow the empty frypot to ignite.
4. Removal of other components and/or repositioning the fryer
may be necessary to gain access to the bottom of the float
switch (see Figure 14). Remove the side access panel if
applicable.
5. Disconnect the two-pin connector from the float switch (see Figure 15).
6. Using a pin-pusher push the pins of the float switch out of the connector.
7. Remove the insulation from the old float switch wires and reuse on the new float switch.
8. Remove the retaining ring at the top of the float (see Figure 16).
9. Remove the float barrel from the shaft (see Figure 16).
10. Carefully loosen the compression fitting around the bottom of the float switch (see Figure 14).
11. Carefully remove the float switch shaft by pulling it through the bottom of the frypot. Retain the mounting
hardware for reassembly.
12. Feed the new float switch wires from the top side of the frypot.
13. Apply Loctite™ PST 567 or equivalent sealant to the threads of the replacement and loosely attach the
compression fittings.
