Questions & Answers

For Whirlpool Washer Timer - 60 Hz (Part Number: OEM18039495)

Tom for Model Number LSQ9030PQ1

Hello, I was told the part number for my model LSQ9030PQ1 was WPWP8557301. I ordered it and installed it. The fills the machine with water and moves to the next cycle however that's where it stays does not agitate. The vendor replaced it and does the same thing. I found the timing drawing in the machine shows the part no. 8557303.Was this replaced by 8557301? Did I get the wrong part number? Is there a relay or switch that maybe bad? Thank you, Tom

1 Answer

Tom, the timer WP8557301 is used with the model number provided. However, as it will not go into agitate after filling, the pressure switch W10337780 would need to be tested for continuity from the violet wired terminal to the tan wired terminal. If it does not have continuity after the water has stopped filling and the power cord is unplugged, the pressure switch has failed. If it does have continuity, the next step would be testing the lid switch WP8318084 for continuity when the lid is down. If there is not continuity, the switch has failed.

Dave for Model Number LSQ9030PQ5

Hello, it appears as though the plastic tip of the timer shaft (the piece that attaches to the knob) has broken off. I can still work the washer by turning the knob to the correct location, removing the knob and pulling out the shaft, by hand, to start the cycle. As I look at the diagram, it appears as though the only option is to replace the entire timer. That's a high price to replace a small plastic tip. Is there another part that might hold the knob to the timer shaft? Thanks.

Sopan123 for Model Number westinghouse washer timer 3951702e

a comment first: great videos, but i noticed in the timer replacement vid, the tech did not replace the knob keeper black plastic lock shaft as he reassembled the unit. oops..im sure its no worries, but i just thought id tell you in case you were a perfectionist...:) My question: What do the letters after timer part number signify? like 3951702 "a", or "e"? important to the application? or just "what factory built", type info. thanks

1 Answer

Hello sopan123. First thank you for the comment. As for the black retainer not being reinstalled, the new timer comes with a new one so there is no need to reinstall the old one. The numbers on the timer are manufacturing and revision numbers and should not apply to the timer working properly in your unit in most cases. Hope this helps.
