In order to prevent damage to the extendable
telescoping interior oven racks, the EOC will not

perform a self clean cycle until the racks are removed.
A rack sensing switch mounted in the rear of the oven
liner signals to the EOC that the racks have been
removed. (Photo A)
When the oven racks are installed the rear edge of the
rack pushes against a pivoting rod on the rack sensor

assembly causing a cam on the rod to depress the

sensor switch. When the switch is depressed the switch
contacts are open. As long as the switch contacts are

open the EOC will assume that the racks are installed in

the oven.
When the racks have been removed the cam of the
sensor rod releases the pressure on the rack sensing
switch allowing the switch contacts to close.
When the EOC detects that the rack sensing switch
contacts are closed it will allow the self cleaning cycle to
operate.

If the customer starts a self cleaning cycle without
removing the racks a message on the EOC will
illuminate instructing them to remove the racks.

If the racks have been properly removed but the EOC
displays the message then the failure
REMOVE RACKS
could be caused by defective switch contacts, wiring
harness connections, stuck sensor rod assembly or
defective EOC.
Examine the sensor assembly rod to be sure it can
move freely. Also inspect the metal plunger cover on
the switch to make sure it has not stuck. The sensor rod

assembly can be removed for cleaning and lubricating if
necessary.
If the sensor switch becomes stiff or hard to depress
the metal cap may need lubrication on the underside at
the contact point of the switch plunger.
Use only an approved , water based graphite lubricant
on the sensor assembly and switch. Part number is
