Controls at the unit cooler
I opened the electrical sections at the unit cooler and checked the existing temperature control, defrost timer and wiring. The wall thermometer and the unit-cooler housing are shown before the control work.
Installing the Penn control
I mounted the replacement Penn temperature control, connected its wiring and routed the sensing lead at the unit cooler. The defrost timer and terminal connections were left accessible for a final check.
After the control and wiring work, the electrical covers and unit-cooler area were put back in order. The invoice total was $537, with a 6-month warranty on parts and labor.
