Troubleshooting Guide
A
Power cord
disconnected
Confirm proper voltage at outlet.
Plug in power cord.
B
Breaker is
tripped
Unplug griddle and check line voltage at outlet.
Reset breaker.
C
Temperature
Controller
If 24VAC is on secondary side of transformer, check power input terminals of Temp
Controller J2-1 & J2-2.
If 24VAC is at terminals, replace Temp Controller.
If 24VAC is not at terminals, check for broken wires or poor crimps at the terminals.
If no 24VDC at the terminals, measure across the controller outputs J7-1 and J7-2 for
24VDC.
If no voltage, replace controller.
If there is voltage, check for poor crimps or loose wires at the terminals.
Fuses
Check for loose or blown fuses.
Wiring
Inspect wiring for damage, opens and/or shorts. Inspect ground and wire to wire
connections.
Note* Unit has a digital controller, if voltages, fuses and wiring appear to be in order,
try cycling power.
Transformer
Check for 24 Volts from secondary side of transformer. If input to transformer is
present and there is no output, replace transformer.
D
Error Code
E001 or E002
on display
E001: Open Temp (RTD) sensor J3-1 & J3-2. Check terminals for poor crimping.
E002: Shorted Temp (RTD) sensor J3-1 & J3-2.
If RTD checks good, reconnect RTD and cycle power. Is error code still present?
Replace Temperature Controller.
E
Over temp
indicator
If griddle is not warming up or holding a set point temperature, cycle power.
Check Over Temp RTD for proper values at current temperature.
If temp/resistance values match RTD, replace Over Temp Thermostat.
If values do not match RTD, replace Over Temp RTD.
If Over Temp and Heat light are on and griddle is not warming, cycle power.
If Over Temp light goes out, monitor griddle to see if it over temps again.
If temperature is greater than 50 degrees different than measurement device, verify
measurement device.
If measurement device appears to be accurate, measure RTD.
If RTD measures normally, replace temperature controller.
If RTD measures out of specifications, replace RTD.
F
Fault light
flashing
If burners did not ignite, check gas pressure, cycle power.
If burners did ignite and unit is heating, check for poor connections in the harness at
the fault timer relay.
