During The Fill Mode

Line voltage is supplied to the air valve. This causes the valve to open so that water can flow into the chamber.

During The Heat-Up Mode

When the Heat-Up Mode begins, the PC board stops the current flow to the air valve. This allows the valve to close. The PC board opens the air valve three times during the Heat-Up Mode to release air from the chamber (this prevents vacuum-effect).  The temperature & pressure will drop slightly each time the valve opens & purges the air from inside the chamber

During The Sterilization / Vent / Dry Modes

There is no current flow to the air valve. The valve is closed.

Troubleshooting The Midmark Air Valve

If Steam is Escaping Thru the End Of The Condensation Coil Located Inside The Water Reservoir beyond the purge cycle, then The Air Valve is defective and Needs To Be Replaced
