GENERAL
This procedure contains information and instructions for inspecting, testing and repairing the CK
Dual Oven Assembly. Refer to WP 0037 00 for repair parts information.
INSPECT
Inspect the oven base, ovens and fan assembly for loose hardware, damaged rivets and broken
or loose welds. Inspect base casters for smooth operation. Tighten loose hardware. Refer
broken or loose frame welds or damaged rivets to Direct Support maintenance.
TEST
Fuel Line: Refer to the troubleshooting procedures in the MBU manual to determine if the
problem with the MBU is caused by lack of fuel. Check the fuel line connection at the wall to the
Mechanical Room. Check all hose assemblies on the back of the oven assembly for signs of
fuel leakage. Replace the hose assembly using the replacement procedure in the following
section.
24 VDC Electrical Cable: Refer to the troubleshooting procedures in the MBU manual to
determine if the problem with the MBU is caused by an absence of 24 VDC. Remove the power
connector at the MBU and check for 24 VDC. If voltage is present, recheck the procedures in
the MBU manual. If 24 VDC is not present, remove the connector on the ceiling duct labeled 28
VDC and check voltage. If voltage is present, repair the cable using the repair procedure in the
next section. If voltage is not present refer to the test procedure in WP 0018 00.
Casters: Attempt moving the Dual Oven Assembly with the casters unlocked. It should move
freely without binding of the casters. Move the Dual Oven Assembly in all directions to isolate
the problem to a particular caster. Check for foreign material in the caster flanges.
