TROUBLE DIAGNOSIS
If the vacuum cleaner fails to operate the trouble
lies in one of three areas; the power source, the low
voltage switch system, or the vacuum cleaner motor.
This is the order in which the trouble should be
examined .
1. Check first that the Motor Home is receiving
120-volt power to the external power cord . Next
check the circuit breakers in the living area electrical
compartment . Finally make sure the vacuum cleaner
is securely plugged into the receptacle under the re-
frigerator module .
