Review on 🔍 Improved SEO: Johnson Controls A421ABC-02C A421 Series Electronic Temperature Control, -40°F to 212°F Range, SPDT by Craig Galante

The new A421 is a major improvement over the A419. There is now an on/off setpoint and a permanently on backlight. I welcome these changes. For people familiar with the layout and use of the A419, this will work just fine. I'm using this to revitalize an old bar fridge that had analog controls that no longer worked. Since the fridge is good, that saved it from a landfill. It came with a pre-installed power cord and was ready to use right out of the box. Fast delivery from the beverage factory.
