Repair procedure
hu
A. Missing electrical power supply
1. Verify characteristics of the electrical system (120V - 60Hz)
sl
2. Check integrity and functionality of the switch
3. Check integrity of the line fuse
tr
B. Incorrect adjustment of the possible control device (thermostat)
hr 1. Check that control device adjustment is correct (for example the temperature set on the thermostat must
be greater that room temperature)
lt
C. Defective control device
1. Replace the control device
lv
D. Interrupted or defective motor winding
et
1. Disconnect the heater from the electrical power supply
2. Detach the control panel and remove the wires powering the motor
ro
3. Connect the ohmmeter lead wires to the blue and brown wires and verify that the motor resistance is not
null. If this were not the case, the motor is defective and must be replaced. Properly adjust the ohmmeter

E. Blocked motor bearings
1. Disconnect the heater from the electrical power supply.
uk 2. Detach the control panel and remove the wires powering the motor
3. Replace the defective motor with an operational original spare part
bs
F. Burnt motor condenser
1. Operate in the same was as the previous case
el
G. Seized fuel pump
zh
1. Remove the upper movable mantle
2. Grab the fan and try to rotate it. If that is not the case, disassemble the pump and rotate the shaft using
pliers
3. If its rotation is impossible, it means the pump is seized and must therefore be replaced otherwise it
means that the motor bearings are ruined and therefore operate as described in point E
