#19390 ELECTRONIC TIME / TEMPERATURE CONTROL
CONTROL ERROR CODES
Error codes are provided to aid in determining the nature of common oven failures and to inform the user of
possible safety or performance problems. Each error has an associated code number that is displayed in the
time digits when the error occurs. The control also sounds a series of attention tones. The control must be
powered down to clear the failure mode.
If a service call is received, sighting any of the following “Error Codes,” please instruct the customer to turn the
oven off and wait for service.
Prior to replacing any of these parts, all the wiring and voltages to the controller should be verified.
ERROR CODE #
ACTION TO BE TAKEN
F1
Replace the T/T Controller (#19390)
F2
Oven temperature has exceeded 551°. Check actual oven temperature and resistance
of RTD Sensor and replace if necessary.
F3
The RTD Sensor (#15856) may have an open circuit. Check the resistance and
replace if necessary. If F3 still appears, replace controller.
F4
The RTD Sensor (#15856) may have a short circuit. Check the resistance and replace
if necessary.
F5
Replace the T/T Controller (#19390)
F6
Replace the T/T Controller (#19390)
F7
Replace the T/T Controller (#19390)
