SOURCE: How do turn the temp up on a norlake walkin?

They are usually mounted on the front panel of the evaporator or mounted on the wall behind the evaporator.There is a possibility that the temp. control is at the condenser,and the sensing bulb was slipped thru the wall.Look for the bulb at the back of the evaporator and follow the cap tube.

Check the evaporator coil for frost buildup on the back. Check for frost on the suction line, the biggest line returning to the compressor. If frost is evident at these places you have a defrost system problem. These systems have a defrost timer that defrosts the coil at preset times. Check the timer for proper operation by marking the position of the dial and check back to see if it changes. If it does not change position the timer motor is most likely bad. If the dial is not rotating automatically you can manually turn the dial in the direction of the arrow and put it through a defrost cycle.

You have to defrost the coil by turnning of the unit and to make it faster leave the inside fan/s running.But if it's building up ice and the fan/s inside works ,is most probably that the unit is low in refrigerant(freon) , or the defrost system is not working.
