Replacing Thermostat - Dometic A552 Service Manual

- Thread back new sensor wire.
Practical way to do it:
From the back panel side, insert a 4x100 standard screwdriver through
the lead bore. Slightly push the flat connector of sensor insulation
socket onto the edge of the screwdriver, secure with insulating tape.
Fold back the end of wire with insulation socket by 180°. Using the
screwdriver, pull the wire through the bore, then using that pull through
the other end of the wire as well. (Fig 73, 74)
When pulling through, pay attention to the position of the lead rubber
gasket. If it falls out, it must be put back in the bore by all means.
- Place the sensor head in the nest of the sensor cover, screw the cover
back in place.
- Place the 2 plugs back in the bores of cover.
- Push back the sensor wires onto the flat connectors of the printed circuit
board (Sensor). The sensor is not sensible to the two wires reversed.
- Screw electrical cover back on.
- Check electrical insulation resistance according to section 2.3.3.
