DANGER

Electrocution can cause death or serious injury. Burns from hot or cold surfaces can cause serious injury. Take precautions when servicing this unit.

•Disconnect the power source.

•Do not stand in standing water when working around electrical appliances.

•Make sure the surfaces you touch are not hot or frozen.

•Do not touch a bare circuit board unless you are wearing an anti-static wriststrap that is grounded to an electrical ground or grounded water pipe.

•Handle circuit boards carefully and avoid touching components.

To measure the start winding resistance, measure across the C and S pins.

To measure the run winding resistance, measure across the C and R pins.

Also check S to R and you should get the sum of the run and start windings.

To ensure the windings are not shorted, check the S and R to ground.

THERMISTORS

For all models, one type 2 thermistor is mounted to the sidewall.

Reed Switch

A reed switch is mounted to the underside of the cabinet and a magnet is mounted to the door. When the door is closed, the magnet trips the switch which turns the light and display off. For glass door models the display remains on unless toggled.

IMPORTANT

The U-Line ADA24R models employ both a 12VDC evaporator fan assembly and condenser fan assembly. The motors are powered by a 12VDC power supply located in the base of the unit. These fans are designed to operate in conjunction with the compressor and should be running whenever power is applied to the compressor electricals. These motors do not require external lubrication and do not overtighten the mounting screws upon installation (tab breakage could occur).
