Frigidaire atf7000fe - Affinity 3.5 Cu. Ft. Front Load Washer Technical Data Sheet page 4

Test
Test 6: 1. Is the loading door closed?
2. In the J2 plug on the control, measure voltage
from the black wire to ground with power on.
Test 7: 1. Remove the door lock assembly and measuere
the resistance of the PTC.
Test 8: 1. Disconnect the plug from the drive motor and
measure the resistance pins 4 & 5 in the motor.
Test 9: 1. Remove the belt from the motor and spin the
motor pulley. Does the motor spin free?
2. Spin the tub pulley. Does the tub spin free?
3. Disconnect the plug from the motor and
measure the resistance of the windings (pin
1 to pin 2, pin 1 to pin 3, pin 2 to pin 3). All
readings should be between 4 and 6 Ohms.
Test 10: 1. Remove the belt from the motor and spin the
motor pulley. Does the motor spin free?
2. Spin the tub pulley. Does the tub spin free?
3. Disconnect the plug from the drive motor and
measure the resistance between pins 4 & 5
in the motor.
4. Disconnect the plug from the motor and
measure the resistance of the windings (pin
1 to pin 2, pin 1 to pin 3, pin 2 to pin 3). All
readings should be between 4 and 6 Ohms.
Test 11: 1. Communication problem. Check the wiring
between the control board and the speed
control board.
Test 12: 1. Check the resistance of the NTC. Is it
around 50K ohms?
Test 13: 1. Have the power company check the
frequency of the incoming power. If correct,
replace the control board.
Test 14: 1. Check the resistance of the heating element. It
should be approximately 14 ohms.
2. Check the resistance between ground and both
heater terminals. It should be open when the heater
terminals are disconnected.
Test 15: 1. Check the resistance of the tub NTC. Is it around
4.8K ohms?

Correction
No. Close the door.
Yes. Go the step (2).
0 volts. Check the door strike. If good, replace the
door switch assembly.
120 volts. Replace the control board.
Shorted or open. Defective door lock assembly.
Reads around 1500 Ohms. Defective control board.
If the reading is between 105 & 130 Ohms, replace the
speed control board.
If the meter reads other than between 105 & 130 Ohms,
replace the motor.
No. Replace the motor.
Yes. Go to step (3)
No. Check the tub bearings.
Yes. Go to step (3)
If the readings are correct, replace the speed control
board.
If the readings are incorrect, replace the motor.
No. Replace the motor.
Yes. Go to step (3)
No. Check the tub bearings.
Yes. Go to step (3)
If the meter reads other than between 105 & 130 Ohms,
replace the motor.
If the reading is between 105 & 130 Ohms, Go to step (4)
If the readings are correct, replace the speed control
board.
If the readings are incorrect, replace the motor.
Wiring bad. Correct wiring problem.
Wiring good. Replace the control board. If the problem is
not corrected, replace the speed control board.
No. Replace the water inlet valve assembly
Yes. Replace the control board.
If the readings are incorrect, replace the heating
element.
No, replace the heater assembly.
Yes, check the wiring.
