2a) Main disconnect on the dryer is turned off.
3a) OL11 (overload #11) tripped.
4a) Fuse #1 is blown.
b.POSSIBLE SOLUTIONS;
1b) Verify main line voltage to dryer
•If line voltage is present go to paragraph #2b below.
•If line voltage is not present check fused disconnect and retest. 2b) Attempt to turn the dryer main power handle to the “ON” position.
•If the switch does not engage, verify that sprinkler power is “ON” (“RED” light on main door).
•If “no,” refer to paragraph #1b above.
3)Open main enclosure and verify that OL11 has not tripped.
•If yes, check circuit, restart and test.
•If no go to section #3 on page 54.
