E51: Motor Relay failure

E51

Motor Relay stuck open, locked rotor, harness, low power supply, Thermal Limit-
er – open, and Motor Centrifugal Switch -1 stuck open or closes.
Checks to perform:
Turn ON the dryer and measure the continuity
between J2-1 and J2-2 Connectors of Electronic
Control Board. Is continuity there?
Measure resistance between the connectors J2
terminals of the Electronic Control Board and the
appliance body. (See Fig. 1) Is Resistance value not "0"?
Detach the connectors and measure between the
terminals (5, 4 & 3 ) of motor and the earth contact.
See Figures (2 and 3) Is Resistance value not "0"?
Detach the connectorfrom the Motor and measure
the resistance between terminals (5 4 & 3).Check
Resistance value are in between "2.6 Ω to 3.2 Ω"? See
Figures. (4 and 5)
Check Inlet Thermal Limiter for the continuity?
Check the Centripetal Switch of Motor is working
mechanically (stuck in open or closed position)?
Replace the Electronic Control Board and repeat the
Diagnostic Cycle to check for any further alarms.
