A nursing center’s kitchen, and a Continental 2F two-door reach-in freezer with an electric defrost circuit rated at 9.6 amps.

Behind the grille, the defrost timer: a mechanical clock motor turning a dial with trip pins, the same design that’s been in reach-ins for decades. If that motor stops, the timer stops where it is, and either defrost never comes or it never ends.

Its replacement is an Intermatic electronic defrost timer. It still has a dial you can read, but the switching is solid state and there’s no clock motor to wear out.

Two days later we were back for the reach-in next to it, a Hoshizaki RH2-SSB refrigerator, and it got a new electronic timer too, mounted beside the old one.

That box’s condenser coil.

And a thermometer reading 37.2°F.

A defrost timer is a cheap part with an expensive failure. In a kitchen where the boxes are the same age, have them looked at on the same visit.

If it heats or cools, we handle it. 📞 718-802-1700
