Appliances seem pretty tame for this site, but this is the only forum I am a member at, so...
I've been meeting 4 wire fans in refrigerators lately. I measured about 13 volts DC that the controller board was using to try to get a fan to run yesterday. I assume the motor is bad and will replace it today but, I wonder if anyone here knows what kind of fan motors the manufacturers are using lately and what kind of drive signal is proper for them. ps, this is a General Electric brand side-by-side ref/freezer, 2002 year.
If I may rant for a moment, I wish they would just use the old 4 watt 120 VAC motors connected to the compressor leads instead of complicating the job with a microprocessor, but they didn't, so it's up to me to keep learning.
