Motor; Door Interlock; Canister Filling Pump (Versions With Canister In Upper Section) - Electrolux EDR1000NEW Service Manual

7.6 Motor

1 – Fan (inclined blades for cold air circulation)
2 – Belt tensioner
3 – Motor
4 – Fan (straight blades for warm air circulation)
The motor group consists of a belt tensioner (2), two fan blades (1
and 4) for circulating cold and warm air respectively, fitted to the
motor shaft using bolts, and a single-phase asynchronous motor
(3) featuring an overheating safety cut-out.
Important: when assembling the fan blades to the motor, do
not reverse their positions, as this would cause incorrect air
circulation inside the dryer.
The efficiency of the motor can be checked by measuring the
resistance across the windings:
Winding A 29 ohm approx. (contacts 1-3)
Winding B 29 ohm approx. (contacts 2-3)
The motor is powered by the electronic board via a relay (which
determines the direction of rotation) and a triac.

7.7 Door interlock

The door interlock is an electromechanical device which powers the electrical loads only when the door is
correctly closed and the programme selector knob is turned (ON/OFF - closed).
The interlock features a child safety device so that, in case of necessity, the door can be opened by
pressing from inside the appliance.
When the door is open, the
button on deviator A is held down
by lever B; in this position,
contacts 1-2 are closed.
7.8 Canister filling pump (versions with canister in upper
section)
The pump is actioned by a synchronous motor with a power of about 17W. The
function of the motor is to pump the condensation water from the sump to the
canister. The pump, too, is powered by a triac.
The resistance of the stator winding is approximately 750 Ω.
SOI/DT 2003-12 dmm
When the door is closed, the latch D
rotates spindle C, thus releasing lever
B; the button on the deviator A changes
position, closing contacts 1-3.
