External Thermal Protector

Check for continuity across the thermal protector ter- minals. Before testing the external thermal protector, ensure the thermal protector had enough time to cool off and reset. If no continuity is present across the terminals, replace the thermal protector.

Potential Start Relay Mounting Position

Always check the relay for correct mounting position before continuing with the following continuity check.

•Relay terminal 2 and 5: No continuity, broken coil, replace relay.

•Relay terminal 1 and 2: No continuity, contacts are open, replace relay.

Start Capacitor

Start Capacitor: BUNN P/N# 39804.0004

Rating: 243-292 MFD 165V 50/60HZ

Disconnect the start capacitor from the system. Re- move the bleed resistor. Use a capacitance

meter to measure the capacitance. The capacitance value should be the rated value

minus 0% to plus 20%. If it is outside of this range, then the start capacitor needs to be

replaced.

Run Capacitior

Run Capacitior: BUNN P/N# 44820.0004

Run Capacitor: 35 +/-5% MFD 425V 50/60HZ

Note: Use a 20,000 ohm resistor set-up to discharge the capacitor before removing from the machine. By doing this, will avoid possible damage to the capaci- tior, measuring device and risk of electrical shock.

Once the capacitor is properly discharged, use a ca- pacitance meter to check the capacitance value. The value should be within 5% range of the marked ca- pacitior value.
