DIAGNOSTIC CHECKS

WARNING: CERTAIN PROCEDURES IN THIS SECTION REQUIRE ELECTRICAL TEST OR MEASUREMENTS WHILE POWER IS APPLIED TO THE MACHINE. EXERCISE EXTREME CAUTION AT ALL TIMES. IF TEST POINTS ARE NOT EASILY ACCESSIBLE, DISCONNECT POWER AND FOLLOW LOCKOUT / TAGOUT PROCEDURES, ATTACH TEST EQUIPMENT AND REAPPLY POWER TO TEST.

1.Check voltage across heating element wires at limiting and regulating contactor terminals.

A.If voltage is correct, check current draw (step 2).

B.If voltage is not correct, check the following:

1)Voltage supply to steamer.

2)Fuses or breaker blown.

3)Power to contactor coils.

4)Contactors not pulling in. (Mechanical)

2.Check current draw (amps) through heating element lead wires using an amp clamp meter.

A.If current is correct, then heating element is ok.

B.If current is not correct, check element resistance (step 3).

3.Remove one lead wire of each heating element from the regulating contactor and check the individual element resistance using a VOM.

A.If resistance readings are not correct, replace heating element.
