Notes:
• Always check for pin back-outs, pinched or damaged wires before
replacing components.
• Determine whether failure is caused by the component, main control
board or wiring. Contact TID before replacing main control board.
• Refer to Service Manual for additional information.

Deactivate: Press + for up to 10 sec. Diagnostic Mode will automatically deactivate after 5 min. of inactivity.
Note: Silence alarm.
• Tests marked with "*" may not be applicable to this unit and will not be displayed in Diagnostic Mode.
• Tests displayed in diagnostic mode but not described below are for internal purposes only; advance through.
• View UI display for "on," "off," "CL," "OP," "SH," "LO," "HI" or numerical results of tests.
• Listen for operating sounds; feel for heat or air flow as appropriate to determine results of tests.

IMPORTANT SAFETY NOTE
The information provided herein is designed to assist qualified repair personnel only. Untrained persons should not
attempt to make repairs due to the possibility of electrical shock. Disconnect power cord before servicing this appliance.
IMPORTANT
If any green grounding wires are removed during servicing, they must be returned to their original position and
properly secured.
CAUTION
All electrical parts and wiring must be shielded from torch flame. DO NOT allow torch to touch insulation;
it will char at 200°F and flash ignite (burn) at 500°F. Excessive heat will distort the plastic liner.
