[. . . ] You should obtain the following readings, plus or minus 10%: RM2310 92 RM2410 92 RM2510 7 5 RM2610 48 RM2810 44 RM2452 69 RM2453 69 RM2552 69 RM2553 69 DC VOLTAGE REQUIREMENTS The operational range is 10. 5 to 15 volts DC. Check for proper voltage at the terminal block or blocks at the back of the refrigerator. The power supply to the refrigerator must be fused. DC COMPONENTS SWITCH (BOTTOM MOUNT CONTROLS) A. For the DC mode, continuity should exist between terminals 1 and 1A and 2 and2A. (3-Way Models Only) For the AC mode, you should have continuity between 4L and 4A and 5N and 5A. RM2310 & RM2410 SWITCH ASSEMBLY DC Mode AC Mode DC Mode AC -Mode B. The RM251O/RM261O/RM2810 selector switch should be checked for continuity in the following manner. Remove all wires from the assembly. For the DC mode, continuity should exist between terminals 1 and IA and2 and 2A. For the gas mode, you should have continuity between 3 and 3A. For the AC mode, you should have continuity between 4L and 4A and 5N and 5A. RM251O/RM261O/RM2810 SWITCH ASSEMBLY Gas Mode DC Mode \ AC Mode DC Mode AC Mode Gas Mode SWITCH (TOP MOUNT CONTROLS) Remove all wires from the assembly. For the DC Mode (3-Way Models ONLY), continuity should exist between terminals 5 and 5a and 6 and 6a. For the AC Mode, continuity should exist between terminals 1 and la and 2 and 2a. For the Gas Mode (on refrigerators equipped with automatic REIGNITERS ONLY), continuity should exist between terminals 4 and 4a. RM2452/RM2453/RM2552/RM2553 SWITCH Gas Mode AC Mode 1 `DC Mode Gas Mode IGNITER A. MODEL RM2310, 2410, 2452, 2453 When the button is pushed, a spring loaded striker creates a spark. If there is no resistance when pressing the button, the piezo igniter is defective. B. MODEL RM2510, 2610, 2810, 2552, 2553 Check that the switch is in the gas mode and is completing the circuit. Next, verify proper voltage at the positive (+) and ground (-) terminals of the igniter. The reading should be within one volt of incoming voltage at the terminal block. HIGH VOLTAGE Disconnect DC power at the terminal block. Reconnect DC power, the igniter should produce a sparking sound. ON MODEL RM2510, 2610 AND 2810: With the igniter producing spark, set the meter on 20 volts DC or lower scale, connect meter leads to L and ground terminals on the igniter. The meter should read a pulsating voltage. The pulsating voltage allows a lamp to illuminate on the front of the refrigerator to advise the customer spark has been produced. ELECTRODE Do a visual inspection for cracks or breaks on the ceramic insulator. Also, verify the mounting bracket is attached properly to the electrode.
