PROBLEM
The pressure relief
valve opens.
The motor will not
run.
POSSIBLE CAUSE
1. The tank pressure exceeds the
normal rating pressure.
2. The pressure switch is stuck.
1. Tank pressure exceeds the
preset pressure switch limit.
2. The fuse is blown or the circuit
breaker tripped.
3. The check valve is stuck in the

Check for proper fuse; type T fuse
is acceptable.
Check for low voltage and proper
extension cord size.
Disconnect other applications from
