At this time, also inspect the printed circuit

board for burned marks or damaged board

components using SERVICE BULLETIN

(pages A-l l-3 to A-l l-5). Whenever

remember to verify the heating element’s ohms

resistance. A shorted 120 volt heating element

can cause permanent printed circuit hoard

failure. (See pages A-l l-3 to A- 1 l-5)

After diagnosing the heating element, insure

that all of the connections on the module

board are inserted correctly and that there are

no damaged leads that could cause circuit

board failure.
