Glad we could help. Hope it's working like a good Harman should!Vacuum (differential) switch it was! Got it today ($ 50) and works like a champ! Thanks all. Great info and huge $$$ saver!
You can also call Harman directly for tech support. 800 number is on their website. Hit 3 and 3 when connected.Your correct on the sensor needs to be hooked up. I never knew that before. With a combo of dealer techs and the tech speaking to Harman direct and me tinkering around the stove, it's humming along fine. That's one advantage the Englander owners have is a direct line to great tech support. I would not rule out owning one in the future.
Well it's possible that the new switch is bad. If not blower motor may have a bad winding or It could be voltage source for high fan operation has failed. I'd start simple with a voltage measurement at the switch. If it's good jump the switch on the high side and see if the motor works or you can check continuity through the switch. If you have voltage and the switch is good then it's likely the motor if it's wired directly off the switch. don't know enough about the circuit to comment decisively on that though.while I'm on a roll I thought I might ask one more question. Only low blower works (for about a year now). Changed hi/low switch but no difference. When you move switch to hi position the blower just stops until you move back to low position (even with new switch). It isnt the end of the world for now, but my fear is low will also eventually stop and so will my options to run the stove. Thanks again
The vacuum switch or low draft sensor, senses draft in the firebox.. If the door is not shut, ash door, or hopper lid, or if the exhaust is blocked, or bad combustion motor, then it won't feed pellets.. It's a safety feature.. maybe the vacuum line is plugged or leaks..Also check for plugged "muffler " in the hopper, this senses pressure in the hopper and is connected by hose to the vacuum switch..
