Possible Fault Conditions Possible Solutions
Check resistance of Outlet Control Thermistor, and check wiring for
short circuit across Thermistor connections. Resistance should be
between 4.9K Ohm and 6.2K Ohm at room temperature (68-77° F or
20-25° C). Replace Outlet Control Thermistor and/or wiring and retest.
Check resistance of Inlet Control Thermistor, and check wiring for
open circuit. Resistance should be between 47K Ohm and 66K Ohm
at room temperature (68-77° F or 20-25° C). Replace Inlet Control
Thermistor and/or wiring and retest.
If motor runs continuously with power applied check for short circuit
across motor relay (RL2), or L1 applied to motor relay output (J3-1)
with cycle stopped. If motor does not start when "start" key is pressed,
check for open circuit between L1 and motor relay connection (J3-2). If
no wiring problems found, replace Electronic Control Board.
Check connections between Electronic Control Board and Interface
Board. If no wiring problems, replace Electronic Control Board or
Interface Board.
Check if correct Interface Board console and Electronic Control Board
are installed. Replace appropriate hardware.
Check if correct Interface Board and console are installed. Replace
Interface Board and/or console.
Replace Electronic Control Board.
Replace Electronic Control Board.
Check frequency of line voltage.
Check amplitude of line voltage.
Check amplitude of line voltage.
Check wiring at terminal block for L1-N-L2 wired incorrectly.
Replace Electronic Control Board.
Check vent restrictions and resistance values of Exhaust Control
Thermistor and Inlet Control Thermistor.
Check vent restriction, Contact Sensor, and resistance values of
Exhaust Control Thermistor and Inlet Control Thermistor.
Check buttons for activation when pressed. Replace console or
Interface Board as appropriate
