Fuse and Circuit Breaker (Fig. 26)
The electrical system is protected by a 30 AMP fuse
located under the control panel and a 20 AMP circuit
breaker with reset button.
NOTE: It is not always possible to see if the fuse is faulty.
It is recommended that you check for faulty fuses with
a continuity tester, not visually.
