YSCFC SERIES FLATBOTTOM GAS FRYERS

CHAPTER 1: SERVICE PROCEDURES

The probable causes of each category are discussed in the following sections. Troubleshooting guides are included in Section 1.8 to assist in identifying some of the more common problems.

1.7.1 Ignition Failures

Ignition failure occurs when the ignition module fails to sense a flame within the 11-second time delay period and locks out. Turn the fryer off, locate and correct the problem, then turn fryer back on to clear the module lock.

There are three primary reasons for ignition failure, listed in order of probability:

1.Problems related to the gas and/or electrical power supplies.

2.Problems related to the electronic circuits.

3.Problems related to the gas valve.

Problems Related to the Gas and/or Electrical Power Supplies

The main indicator is that an entire battery of fryers fails to light. Verify that the quick disconnect hose is properly connected, the fryer is connected to power, the main gas supply valve is open, and the circuit breaker for the fryer electrical supply is not tripped. Some fryers are equipped with a fryer reset-switch that must be reset each time the fryer is turned off.

Problems Related to the Electronic Circuits

If gas and electrical power are supplied to the fryer, the next most likely cause of ignition failure is a problem in the 24 VAC circuit of electronic ignition systems. If the fryer is equipped with a filtration system, first verify that the drain valve is fully closed. (The valve is equipped with a microswitch that must be closed for power to reach the gas valve. Often, although the valve handle appears to be in the closed position, the microswitch is still open.) If the valve is fully closed, or the fryer does not have a filtration system, refer to the troubleshooting guides in this chapter.

Problems Related to the Gas Valve

If the problem is not in the 24 VAC circuit, it is most likely in the gas valve itself, but before replacing the gas valve, refer to the troubleshooting guides in this chapter.
