Product review (5 stars): Good buy!
My ten year old LG dryer has been cared for quite well but I noticed the past 6 months that the heat wasn't consistent. The sensor dry was leaving clothes damp sometimes then I found that the timed dry selection would dry it super hot but then eventually, the other day that stopped working too. Googled up and found that the most common elements to check for when there's not heat in the dryer is...

1. The Thermal Fuse
2. Thermostat
3. Heating element.

I was lucky enough to get it fixed first time with the thermal fuse. Was a ten min fix, saved myself $$$. Dryer now heating up as normal and sensor dry back on.

Another purchaser did mention that installing via the rear where the air duct was more efficient. I agree. It may be a little nifty to maneuver inside to remove the fuse but once done, very easy to install.
