that are used on our convection ovens. Analysis of the returned controllers proved that greater
than 70% were without any defects.
In order to reduce the percentage of faulty diagnosis, we have formatted the attached
troubleshooting guide that must be used during future service calls where a controller is suspected
of being faulty.
Be sure to follow the key pad testing procedures as outline in Bulletin # B-107-2001 prior to
performing any testing on the rest of the controller circuit so as to eliminate a potential key pad
problem.
If you do not use this guide and your returned controller is found to be functional, then your claim
will be rejected.
Please contact the Garland / US Range Technical Service Department at (800) 427-6668 with any
