(Note: Fan isn't running, even when I push in the door switch. It does run when the freezer is in the cooling mode.)
Thermostat shows continuity at less than 50F (but no ice around it) - Heater shows ~33ohms, but is getting no power.
So, correct me if I'm wrong, the heater thermostat is closed when cold, and breaks power to heater when warm so heater should be getting power now, provided by output of the timer routed through the thermostat. OR does the thermostat control (for instance) a relay which interupts heater power?
Am I correct in the assumption that the defrost cycle is always the same time period, or does the timer stop until the thermostat opens (defrost complete) and then resume operation? Wish I had a schematic!
(The timer has been in the defrost mode while we have been "talking".)
I advanced the timer through several cycles and then heard a sizzling noise and saw the heater had come on. Looks like I have tired heater contacts in the timer??
One clarification - You said, "as long as the thermostat is closed the timer should be running" - does it stop when the thermostat is "open"?
Hi Bryan; I guess you are no longer there. I think I got what I needed and thanks!
