    Hi guys hope this is an easy fix or even just to know what test I can do would be great.
    On our guillotine when you press air bed on nothing comes through the air bed. All switched on via turn switch and lever switch. Motor is running as can feel a draft from underside where fan is. Could it be solenoid and is it easy to test.......cheers.....1986 is year of make with upgraded software

    Since you've said the air turbine motor is working, let's check the air solenoid. Do you have a multimeter?
    Switch off the machine and pull out the solenoid cable plug. Set the meter to the ohms scale check the solenoid pins. if it shows few ohms then it's OK. If it goes to mega ohms then the solenoid is bad.

    If the solenoid is OK, check the supply to the solenoid. Turn on the machine and activate the air bed. Them check the voltage at the solenoid end. Should show some voltage (24V or 42V) if not have to check the relays or SSRs..

    Hope this helps.. :)
