Focus Temp Insta 2001
I recently had the defrost sensor/switch/thermostat go bad on my Waterco/Focus Temp Insta 2001.  I was wondering if you anyone knows of a comparable replacement that could be used in its place.  The Markings on the side are SEO F40-50.  I have been searching but have not been able to find another with the same markings/rating.
