The attached test points are a useful service tool to better determine if the problem is with the keypad,

controller, relay board assembly or other.

The attached pages shows the PIN-OUT test points for the keypad used on the above Garland & US

Range convection ovens.

When servicing a unit with reported erratic or non-responsive controls, test the keypad first.

mode.

I.e. “unit will not turn off”. Unit will not go to OFF mode until oven cavity temperature

drops below 150°F. This is a normal operation of the controller in the auto cool down

mode.
