WARNING: Always perform the Electrical Lockout/Tagout procedure before removing
any sheet metal panels or attempting to service this equipment. Failure to comply with
this procedure can cause property damage, injury or death.
WARNING: Perform the GAS LOCKOUT/TAGOUT procedure before servicing the unit.
1. Perform the CONTROL PANEL REMOVAL procedure for the convection oven.
2. Locate the solenoid.
3. Place the fan control switch in the ON position. An audible click should occur when the
switch is activated. If the solenoid does not cycle, check for proper voltage and ground at
the solenoid as follows:
a. Place a multimeter in the appropriate AC range (220 volts AC or 120 volts AC).
Check for voltage at the solenoid. If voltage is not available, shut off electrical
power to the oven and check continuity between the power switch and solenoid.
b. If voltage is available, shut off electrical power to the oven. Place the multimeter
in the continuity range. Check for continuity between the solenoid ground
connection and a ground. If continuity is not available, check and repair ground
connections.
c. If continuity is available, perform the SOLENOID REMOVAL procedure and
check for solenoid orifice obstruction.
WARNING: All gas joints disturbed during servicing must be checked for leaks. Do
not use an open flame. Use a hazardous gas tester or a soap and water solution
(Bubbles indicate a gas leak). Failure to comply can cause property damage, injury or
death.
4. Reverse the procedures to install the solenoid.
5. Test the oven to verify proper operation.
