10.6 Plate Heater

Symptom: No heat when voltage is applied.

Symptom: Overheats

Tests:

With power removed from the HLZ , measure resistance between terminal 4 (white wires) on the latching relay and terminal 4 on the plate heater relay. The reading should be 215 to 230 ohms on an HLZ 18; 150-180 ohms on an HLZ 22. Also, check for continuity to the chassis. Resistance seen there indicates a chaffed or shorted wire.

10.7 Air Heater

Symptom: No heat when voltage is applied.

Symptom: Overheats

Test:

With power removed from the HLZ , measure resistance between pin 4 (white wire) on the latching relay and terminal 4 on the air heater relay. The reading should be between 18 and 26 ohms on a 208V unit and 25 and 33 ohms on a 240V unit. Also, check for continuity to the chassis. Resistance seen there indicates a

chaffed or shorted wire.

10.8 Latching Relay

Symptom: Computer calls for heat (dot illuminated). No heat from plate and blower doesn’t operate.

Test:

With power removed from the HLZ and the wire removed from pin 1 or 0 of the latching relay, measure resistance between pins 1 and 0. It should be between 79 and 89 ohms.

10.9 Blower

Symptom: No airflow.

Symptom: Unit overheats; displays PROB.

Tests:

The latching relay is positioned in the HLZ with the 0 and 1 terminals facing the front of the unit.
