Step 5: Check Normal
Operation
1.Set the fryer’s thermostat above 200°F/93°C.
2.Watch to see whether the pilot lights smoothly when the gas reaches the pilot burner.
3.Watch to see whether the main burner lights smoothly without flashback.
4.Watch to see whether the main burner operates smoothly without floating, lifting, flame rollout, or heat buildup.
5.If the gas line has been disturbed, perform a gas leak test, as follows:
a.Paint the gas control gasket edges and all pipe connections downstream of the gas control, including pilot tubing connections, with a rich solution of soap and water. Bubbles in the solution indicate gas leaks.
b.If there are leaks, tighten the joints or screws, or replace the component.
c.Test again for leaks.
d.Repeat this procedure until no leaks exist.
6.Set the thermostat below 200°F/93°C.
Watch to see whether the main burner flame and the pilot flame go out.
thermostat below 200°F/93°C for at least one minute before continuing. On retry models, wait for retry or reset at the thermostat.
•If any component does not function properly, make sure it is correctly installed and wired before replacing it.
•The ignition module cannot be repaired. If it malfunctions, it must be replaced.
•Only trained, experienced service technicians should service intermittent pilot systems.
As the first step in troubleshooting, perform the checkout procedure. Then check the block diagram. If you think there is an ignition problem, see “Troubleshooting the Ignition System” below to isolate and correct the problem.
Following troubleshooting, perform the checkout procedure again to be sure system is operating normally.
Troubleshooting the
Ignition System
Step 1: Check Ignition Cable
1.Make sure the ignition cable does not run in contact with any metal surfaces.
2.Make sure the ignition cable is no more than 36”/0.9 m long.
Troubleshooting—General
The following service procedures are provided as a general guide. For electrical troubleshooting refer to the diagrams included with this manual, or to the wiring schematic on the inside of the fryer door. Keep the following things in mind:
•On lockout and retry models, meter readings between gas control and ignition module must be taken within the trial for ignition period. Once the ignition module shuts off, lockout models must be reset by setting the
3.Make sure the connections to the ignition module and to the
4.Make sure the ignition cable provides good electrical continuity.
Step 2: Check Ignition System Grounding
Nuisance shutdowns are often caused by a poor or erratic ground.
