Product review (1 stars): NOT HAPPY!
This heat element assembly had a defective LOW HEAT sensor which I ended up replacing causing me much time and money since I only needed to replace a $12 sensor. Instead I bought the whole heater assembly as well as exhaust and moisture sensors. I finally discovered the real problem checking every component with a multimeter. NOT HAPPY!

OK... after replacing defective LOW heat sensor that came with the heater assembly this unit works for a few months and then quit again! Power (RED) wire overheated and burned up....SEE PHOTO. VERY UNSAFE. I WILL CONTACT AMAZON FOR RESOLUTION TO THIS. IMO, A VERY INFERIOR PRODUCT WITH POOR QUALITY CONTROL.
