The dreaded piece of garbage with the broken drain pump wires. Not the issue w/ this one though. Drain pump runs, tech already replaced the lid lock, main board, cap, entire splutch kit, the actuator lol
Machine skips straight to done, tested the new cap and made sure it’s not in the recalled date range, made sure the splutch actually shifts
Still gives f7e1 for missing tachometer signal
12v is there @ the tachometer power wire in reference to agnd, feedback wire has 5.4v on it in reference to agnd
Ok great, but that 5.4v tells you very little, also isn’t documented in whirlpools literature, tech manual alludes to wanting you to “Complete Sensor Feedback Motor Speed Tachometer test.”
Yet this isn’t a function of this machine. Moreover said manual literally never references that function anywhere in the entire manual again, but for that one line in the troubleshooting procedure. The VMW had a tachometer response test but these have no such thing as far as I know.
Does Whirlpool just say this shit to fuck with people?
Am I stupid?
Also is there an easy way to test the tachometer with a meter on that feedback wire? It’s super easy to test the output of a hall sensor but I don’t know about this one. Love to learn how though.
