TROUBLESHOOTING ELECTRICAL PROBLEMS

The following guide is intended to be used if a problem occurs during
the use of the SS1-R side wall vent system. At several steps
throughout the guide you will be required to measure 115 Volts with
a voltmeter, (See Diagram T).

Extreme caution must be exercised to prevent injury. If you are
unable to determine the defective part with the use of this guide, call
your Tjernlund distributor or Tjernlund Products direct at 1-800-255-
4208 for further assistance.

Step 1.

Verify that 115V is present between "L1" and "L2"
on terminal strip, (See Diagram T).

Check circuit breaker or fuse

and electrical connections.

SS1-R and appliance are not interlocked correctly or

malfunction of appliance controls. Refer to

electrical diagrams in this manual and appliance
manufacturer's troubleshooting guide.

Replace Timer/Relay,
Part #950-1067.

SYMPTOM 1: SS1-R MOTOR WILL NOT OPERATE

Step 2.

With thermostat calling for heat, check for voltage
between "O" and "R" of terminal strip.

Step 3.

Verify that 115V is present between "M" and "L2"
on timer/Relay.

Remove the external control wire attached to terminal
"O" of the SS1-R terminal strip. This should cause the
