Door Switch; Fuses; Climate Control Heater - Dometic RM2607 Service Tips Manual

D. GAS MODE: Verify that the following components are good: upper circuit board, thermistor and 3-amp
fuse.
Check for voltage during trial-for-ianition at Plug 3, Terminals
the solenoid. If no voltage is present, change the circuit board.
Next, check for voltage to the igniter. If no voltage is present, check the wires. If good, then change
the circuit board.
NOTE: When millivolts to the lower circuit board are 10 * 3, the power to Plug 3, Terminal 4 (blue
wire) will be shut off. If flame extinguishes during the cooling mode, the circuit board will not supply
voltage to Plug 3, Terminal 4 (blue wire) again until the millivolts have decreased to 10*3.
To check the flame sense circuit of the lower circuit board, operate the refrigerator on GAS mode,
then measure the millivolts between J3 terminal and the other wire connection from the thermocouple.
The millivolt meter should read between 25 to 35 millivolts with the gas flame burning. Next, turn the
manual shutoff valve to OFF and watch the millivolt reading as it drops. Note the millivolt reading
when Plug 3, Terminal 4 (blue wire) receives power. It should be 101t 3 millivolts or 7 to 13.
DOOR SWITCH (Only on Models Equipped with Interior Lights)
When the switch arm is depressed, there should not be continuity. When the switch arm is NOT de-
pressed, there should be continuity.

FUSES

The 3 amp DC fuse is designed to protect the circuit board from internal shorts. The 5 amp AC fuse is
designed to protect the integrity of the AC heater circuit from shorts. On 3-way models only, the 35 amp
DC fuse is designed to protect the DC heater circuit integrity.

CLIMATE CONTROL HEATER

Disconnect the wires and do a continuity check. In the OFF position, there should be no continuity.
the ON position, there should be a continuity reading.
To check the heater itself, do an ohms resistance reading. The proper ohms reading is 24 ohms f 10%.
