Beeps Are Not Heard - Whirlpool Catalyst Troubleshooting & Repair Manual

4.

Beeps are NOT heard

If beeps are not heard but associated
LED(s) turn on and off, it is possible
that the beeper circuit has failed or that
the control board has failed. Before
replacing the control board, check
for proper touchpad functioning:
a. Disconnect the power cord from the
outlet.
b. Remove connector P3 and P4 from
the microcomputer board. Using the
table in the tech sheet, measure the
resistance across the switch when the
switch button is pressed. The meter
must be connected with the proper
polarity.
• If using an analog readout: the
resistance reading should go from
infinity (open circuit) down to about
10 or 20 ohms.
• If using a digital readout: the
resistance reading should go from
infinity down to about 2 megohms
- 4 megohms. If available you
could use the "diode test" function
of a digital meter, which will give a
voltage af about 1.2 VDC during
the test.
c. If any switches fail, this test, replace
the key switch/console assembly.
d. If they test OK, replace the control
board.
5. No washer function is activated when
a particular touchpad is pressed.
If the associated LEDs do light up, it is
possible that the control board has failed.
Check touchpad functioning before replac-
ing control board.
