S, SM, AND SMW Oven Error Code Messages…continued

Note 1 F1, F7 Errors are caused by a single loss of communication between the control head and the touch panel. Heat migrates to affect the connector on the control head. The new main power/relay board #35-00-760 has been reprogrammed to keep the cooling fan on until internal oven temperature is 300 degrees F.

Note 2 & 3 Check sensor by taking resistance reading from molex plug on main relay board. A good sensor will read approximately 1050 ohms at 75 degrees F. If out of tolerance by 100 ohms or more replace. Take special care to be sure butt spices are in the air channel in the back and not stuck in the insulation or against oven liner.

When checking sensor also check each lead to chassis ground and to each phase of power line. If grounded or if voltage is present, sensor may read a correct resistance as a loop, but still produce errors. Check lead dress very carefully.
