GOOD PRODUCT
After reading troubleshooting I replaced this unit, however it turned out to be the main board and I replaced the entire unit seeing that it was almost 15 years old.

GREAT SENSOR
to be honest I thought sensors are complicated and expensive. this product proved me wrong. it is easy to install and affordable. can’t wait to show it to my uncle.
