How do I get the solenoid valve on the Cabinet Cooler to stop chattering?
The Model #9017 Thermostat includes a Model #4519 Capacitor. This .002 microfarad capacitor is wired across the leads of the thermoswitch to stop chattering. The chattering is caused by a slow change in temperature inside the enclosure. The capacitor desensitizes the thermoswitch to eliminate chattering.
