TEST PROCEDURES

PROCEDURE

LETTER

COMPONENT TEST

F.When the internal wire is opened in the high voltage capacitor shows an infinite resistance.

G.The resistance across all the terminals and the chassis must be infinite when the capacitor is normal.

If incorrect reading are obtained, the high voltage capacitor must be replaced.

CARRY OUT 4R CHECKS.

ESWITCH TEST

Isolate the switch to be tested and using an ohmmeter check between the terminals as described in the following table.

FTEMPERATURE FUSE OR THERMAL CUT-OUT TEST

CARRY OUT 3D CHECKS.

Disconnect the leads from the terminals of the thermal cut-out or temperature fuse. Then using an ohmmeter, make a continuity test across the two terminals as described in the below.

If incorrect readings are obtained, replace the temperature fuse or thermal cut-out.

An open circuit thermal cut-out (MG) indicates that the magnetron has overheated, this may be due to resistricted ventilation, cooling fan failure.

An open circuit temperature fuse (OVEN) indicates that the food in the oven cavity may catch fire, this may be due to overheating produced by improper setting of the cooking time or failure of the control panel.

GMOTOR WINDING TEST CARRY OUT 3D CHECKS.

Disconnect the leads from the motor. Using an ohmmeter, check the resistance between the two terminals as described in the table below.
