My tumble dryer, an old Inglis model IA84702, started making a squealing noise. I checked videos online to diagnose the problem and ended up disassembling it. I found out that the motor bearings were making the noise, so I found a replacement motor online. The old one is a model: 3395652 motor, and the new one is a WP 279827 model.
The switch and pulley looked completely identical, and I just installed the new one in reverse order as it is written in the instructions. Unfortunately, the settings on the front panel don't work properly anymore. The timer stops the machine when it's on off, but the dryer starts automatically when it's on a time setting, not allowing me to press the start button. Then, the heat settings don't work either. On Low heat, the dryer makes a lot of heat, and smell hot. It worries me a lot. On High heat, it makes no heat at all. So I unplugged everything from the wall and I am waiting for some advice. The door stops the machine and turns on the light like its supposed to, and the drum rotates properly.
I am wondering if, although the harness switch looks the same, the wiring might be different and require modifications. I worked in an assembly job for a while, so I know how to strip and reconnect wires, following instructions, but I don't know how to read electrical diagrams.
Also, both motor switches looked the same (see attached picture), but the new one, 279827, has no colors on the wires. It's only copper wires. I don't know which wires does what on both motors.
I would like some hints, please. Can you tell me if I've got the proper parts and identify what the issue might be? I had to stop working on it for now, because I was too anxious. Any advice would be greatly appreciated.
This website said that the manufacturer of the old motor replaced it with the part I bought: http://www.partselect.ca/PS334304-Whirlpool-279827-Drive-Motor-with-Pulley.htm?SourceCode=3&SearchTerm=3395652
I can learn to do everything with enough time. I learned how to disassemble the dryer myself, and change the motor on my own, so I trust that I can learn how to fix this too.
Thank you very much for your help.
