If the above test does not show a closed circuit, perform the following.
- Check for grease or any foreign material between the Touch Buttons and the contact board. Clean with
an electronic contact cleaner as described above.
- Repeat test above.
- If the contacts are clear, replace the keypad assembly.
- If the circuit is closed, check for 120VAC between contacts N3 and L3 on the main PCB. If voltage
is not present, replace the main PCB.
Wires Are numbered 1 through 14 the molex plug should be numbered.
Voltage output for fan speed
Voltage output from the main PCB to the exhaust fan motor:
Measurements of voltage are average readings, as actual measurements will vary with incoming voltage into the
home. Motor amperage draw 2.7-3.5 depending on the duct run.
Possible Failures
A. Unit dead on arrival
1. Check the keypad to be sure that the Lockout Mode has not been activated (look for the two
LEDʼs) To disable press and hold the HIGH and LOW button for a minimum of 1.0 second.
2. Check voltage between N1 and L1 on the main PCB. The voltage should be 120VAC. If
voltage is not present check the incoming power supply and all wiring connections. A miswired
unit may cause the PCB to fail.
3. Check the Keyboard wiring harness and Molex receptacle for open or loose wires. Make sure
