Versa Grate System – Troubleshooting
In trouble- shooting this system we will be looking at the electrical and the mechanical
part of the system.
The Versa Grate System should be running at all times when the stove is turned on. The
power is supplied to the versa grate motor through the Purple Wire in the Harness.
• Electrical - As an electrical component, the troubleshooting of the Versa Grate
Motor can be broken down to a defective gear motor, a defective control board, or
issues related to the wiring. The Versa Grate Motor has 2 Black wires. One is
connected to the Terminal Block in the back of the stove, making the Common
connection. The other is plugged into the Purple wire in the harness. If the motor
is not running:
 Check to see if there is voltage at the Purple wire in the harness.
 If there isn’t any voltage there, check to make sure the Purple wire is
plugged in properly to the control board.
 If there isn’t any voltage at the control board, the board is bad and needs to
be replaced.
Remember: The stove must be turned on when checking for voltage.
 If there is voltage at the motor and the motor isn’t running, the motor is
bad and needs to be replaced.
• Mechanical – If the motor is running, but the Grate in the stove is not moving
back or forth, there may be a problem in the mechanical components. There are 2
areas to look at. (See figure 18 on page 40 for detail.)
 First see if the Cotter pin is inserted through the Spacer and Shaft/Cage
weldment. This positions the Shaker Plate below the Grate weldment. If
the pin is missing the Shaker plate will not move the way it should. The
Shaker Plate should move back and forth about ¾”. The movement is
Front to Back as you look at the burnpot. To see the pin, pull the Grate
Weldment and Shaker Plate out of the stove.
 The other components that could prevent the Versa Grate from moving are
located in the back of the stove. See the Cam and Versa Grate Collar in
the respective parts diagrams. The York Insert will only have the Cam; all
Freestanding models have the Cam and The Versa Grate Collar. These
attach to the Motor and Cam Connector Rod (Freestanding Models only)
with setscrews. If any of the setscrews are loose, this will prevent the
Versa grate from moving.
