Maintenance
The Groen Convection Combo™ is designed for
minimum maintenance. Certain parts may need
replacement after prolonged use. If there is a need
for service, only Groen personnel or authorized
Groen representatives should perform the work.
If steam or condensate is seen leaking from around
the door, take the following steps:
1. Check the door gasket. Use a 2" strip of paper
closed in between the door and the gasket. If
the paper is not snugly held in place, adjust the
latch pin as indicated in Step #3. Replace the
gasket if it is cracked or split.
2. Inspect the cooking chamber drain to be sure it
is not blocked.
3. Adjust the latch pin as follows:
a. Loosen the lock nut at the base of the latch
pin, and turn the latch pin ¼ turn clockwise.
Re-tighten the lock nut.
b. After adjustment, run the unit in the Steam
Mode to test for further steam leaks.
c. If leakage continues, repeat the adjustment.
d. Continue adjusting the pin clockwise until the
door fits tightly enough to prevent leaks.
Troubleshooting
A. Pilot Burner
Remember that the front control panel will not
operate until the pilot switch has been activated
and the pilot burner flame has been ignited
(green light is on). For details, see Initial Start-
Up on page 11. If the procedure described in
Initial Start-Up has been followed and the pilot
burner still does not light, contact your
authorized Groen Service Agency.
B. Resetting the Solid State Controls
(If problems persist call an authorized Groen
Service Agency)
If the controls stop responding to normal
commands, or the unit is behaving oddly, reset
the controls using the following procedure:
1. Switch off the power by pressing the ON
touch pad.
2. While pressing the COMBO touch pad,
switch the power back on. If no errors are
present, the unit will beep and show four
zeroes in the Time/Status display. If there
are errors, the unit will not beep, but will
display Service Codes, both in the
Time/Status and Cook displays. Note the
Service Codes. Press CLEAR to exit the
Service Mode and refer to the following
explanation of service messages.
C. Service Messages
There are two types of service message:
1. Non-critical error: signaled by three quick
beeps. The SERVICE light comes on for 15
seconds and then goes out.
2. Critical error: signaled by a continuous five
second beep. The SERVICE comes on and
stays on.
If there is a non-critical error you may continue to
operate the unit. As soon as possible, check the
Service Code. Turn off the unit by pressing the
ON touch pad. While pressing the COMBO
touch pad, switch the power back on. Note the
numbers and refer to the Troubleshooting Guide
which follows. Press CLEAR to exit the Service
Mode.
If there is a critical error, the unit will not operate
in its present mode, but it may operate in another
mode. Check the Service Code as instructed
above, then call your authorized Groen Service
Agency.
If the problem continues after you follow the
instructions in the Troubleshooting Guide, call
your authorized Groen Service Agency.
