1.7.4 Replacing the Frypot (cont.)

9.Recover the drain valve, high-limit thermostat, operating thermostat, and burner manifold assembly from the failed frypot.

10.Clean the threads on the recovered parts, apply Loctite PST 567 or equivalent thread sealer, and install them on the replacement frypot.

11.Reverse Steps 1-9 to install the replacement frypot in the cabinet.

For SUFF/UFF Filtration-equipped systems, consult the Decathlon Series Gas Fryers Service & Parts Manual (819-5922), Section 1.7.8, for detailed frypot-removal instructions.

1.8Troubleshooting and Problem Isolation

This section is intended to provide technicians with a general knowledge of the broad problem categories associated with this equipment, and the probable causes of each. With this knowledge, the technician should be able to isolate and correct any problem encountered.

Problems you are likely to encounter can be grouped into these broad categories:

1.Pilot failures

2.Improper burner functioning

3.Improper temperature control

4.Filtration Problems

5.Leaking

The probable causes and corrective actions for each category are discussed in the following sections.

1.8.1 Pilot Failures

When troubleshooting millivolt systems, always check these areas before performing diagnostic checks on either the Robertshaw or Honeywell systems:

A.Inspect all wires and component leads for damage (heat, oil, moisture, etc.). On capillary tube-type thermostats, check for resistance on the thermostat lead wires. Wire nuts and other connectors cannot be present in a millivolt circuit as they can cause resistance. If resistance is found, solder the connectors to the wires or replace the wires.

B.Clean and verify that all wire connections and gas valve terminal connections are tight.

C.Check the length of the pilot flame (it should be about 1½-inches (38mm) long) and verify that it contacts the top one third of the thermopile. Clean the pilot orifice and adjust the pilot strength if needed.

D.Measure thermopile output with no load (i.e., with the thermopile disconnected from the gas valve). Measurement must be made with a multimeter having a 0-1000 DC millivolt (MV) range. Light the pilot and have someone hold the gas cock knob in the depressed position. If the thermopile is a single lead (coaxial) type, measure from the lead’s end contact to its screw-in threads. If the thermopile has two leads, measure across the end terminals. The reading should be within the range of 500-800 millivolts. If not, replace the thermopile.

Performing diagnostic checks on Robertshaw and Honeywell valves are described on the next page.
