J&R MANUFACTURING ROTISSERIE, Operation And Service Manual

HIGH VOLTAGE MALFUNCTION
Remove the electrode from burner.
Check the spark gap and adjust to 1/8” ± 1/32”.
Check the ceramic housing for cracks.
Check the electrode lead wires for cracks or breaks.
Check Terminals E1 and E2 for grounding (Local sensing). They should be no closer
than 1/2” from metal objects, which can cause arcing to ground. If the electrode or
electrode lead wires are faulty, replace the defective parts.
If remote sensing is used, be sure sensor wire is connected to S1, and the E2 terminal
is grounded.
VALVE MALFUNCTION
If the board is powered and there is a spark during the trial-for-ignition period, but the
valve will not open, check the valve for an open coil or other malfunctions. Also check
the voltage rating of the valve (24, 120 or 240VAC) and the B(V1), V2 voltage of the
Fenwal 05-14 being used. Use a voltage tester or voltmeter at Terminals B (V1) and
V2. The voltage here should be the same as the valve. Refer to the manufacturer’s
specifications and replace either the valve or the Fenwal 05-14 so voltage ratings are
compatible.
ERRATIC OPERATION
If the system operates properly for a while but randomly shuts down during the duty
cycle, or won’t operate during “cold” start, check the flame proving circuit with a DC
microamp meter. Typical flame current is 2-20 microamps.
If you have low or marginal flame current, it is possible to get nuisance tripping of the
thermal reset timer. If this is the case, you should relocate the electrodes or flame
sensor into the flame to increase the flame current.
Ignitors that begin with the designation 05-142 are designed to be reset by switching
the thermostat off rather than having to press the thermal reset timer button in the
event of a lockout.
If the ignitor is switched off and on several times in succession, the thermal reset
timer will trip, and it will have to be reset.
NOTE:
If ignition is not achieved after the first two or three attempts, check to insure
that the other components in the system are functioning correctly.
