D. NO DISPLAY CONDITION
NOTE: Regardless of the voltage (120-240 VAC) make sure the voltage selector switch is set to
115 VAC.
1. Check power supply. (Dryer voltage 110v, 208v, 220v) (Circuit breaker box or fuse panel)
2. Check fuse 2 (3/4-amp Slo-Blo) if blown, replace it.
3. Check for voltage at the (J5) 6-pin connector (120 VAC) pin #1 black wire and pin #2 white wire. If no
voltage, check for a loose connection.
4. Check for voltage at the microprocessor pin #6 black wire and pin #3 white wire. If no voltage, check for
a loose connection. If voltage is present, the problem may be a faulty microprocessor.
5. Check for voltage across the computer’s 9-pin connector pin numbers 6 and 3 (110v, 208v, 220v). If no
voltage is evident, problem is bad wire or termination from the computer’s connector pin numbers 6 and 3
to the 9-pin connector (J2) pin numbers 6 and 3. If voltage is evident, problem is faulty computer.
