How to Troubleshoot & Replace Lg AP5211577 / 4974EL1002B Dryer Lint Filter Guide

I have order three parts, guide filter, cover guide, and sensor assembly. My previous cover guide was from two parts, when sensor assembly was one of them. New part ( guide cover ) was all in one piece so I just transfer old metal part of sensor to new cover guide and I don't need that sensor assembly anymore. I have ordered all three parts overnight by Fedex, ordered 15 min before 5pm, so next day it was here. Dryer is fixed, I'm happy. 

Parts shown at the right went in with no problem and dryer works again. 

I replaced the pieces and all the lint was really easy to take the vacuum cleaner extension for the hose and clean out all the stuff inside which with any dryer you should be clean them out once a year. I didn't order the sensor strips that were on the one piece, but they were easy to take off and put back into the new piece saved a bunch of money. 

Watched the helpful videos that were displayed with each part. Took less time than they gap predicted 

I removed 5 screws and pulled the broken door out and installed the new one. Took all of 15 minutes. 

Not the same as the picture but it fits right. I had to remove the moisture bars from the old one and put them on the new one. 

Replacement Filter Guide. 

I ordered the Filter Guide and a Guide Cover. 

The dryer has been working for 3 days now. The thermistor tested good but removed anyway and found probe inside blower had built up lint on it affecting its sensitivity 

Ordered new part. To dryer apart to replace. Put dryer back together and was ready to use.
