Midmark® 1000 Check Valve and Solenoid Test and Repair
The check valve and solenoid are located in the lower compartment.
Compressed air travels from the compressor head though the check valve, which prevents air flushing back into the head. Then air flows through the solenoid. The solenoid allows air to escape for approximately two seconds to relieve pressure from the head, then closes sending pressurized air to the storage tank.
1.Disconnect power.
2.Remove check valve from compressor head and solenoid.
3.Blow out valve with air. If valve is sticking, replace.
