Be careful not to damage sealant. 7. Remove complete inducer assembly from furnace, exposing flue openings. 8. Using field- provided small wire brush, steel spring cable, reversible electric drill, and vacuum cleaner, clean cells as follows: a. Assemble wire brush and steel spring cable. (1.) Use 48 in. of 1 /4 -in. diameter high -grade steel spring cable (commonly known as drain clean -out or Roto - Rooter cable). (2.) Use 1 /4 -in. diameter wire brush (commonly known as 25- caliber rifle cleaning brush). NOTE: The materials needed in items (1.) and (2.) can usually be purchased at local hardware stores. Insert twisted wire end of brush into end of spring cable, and crimp tight with crimping tool or strike with ball -peen hammer. TIGHTNESS IS VERY IMPORTANT. (4.) Remove metal screw fitting from wire brush to allow insertion into cable. b. Clean each heat exchanger cell. (1.) Attach variable- speed, reversible drill to end of spring cable (end opposite brush). (2.) Remove cell outlet plates. IMPORTANT: Replace screws in center panel before cleaning. Insert brush end of cable into upper opening of cell and slowly rotate with drill. DO NOT force cable. Gradually insert at least 36 in. of cable into 2 upper passes of cell. (See Fig. 8.) (3.) (3.) (7.) A91252 Fig. 8-- Cleaning Heat Exchanger Cell (4.) Work cable in and out of cell 3 or 4 times to obtain sufficient cleaning. DO NOT pull cable with great force. Reverse drill and gradually work cable out. (5.) Remove burner assembly and cell inlet plates. NOTE: Be very careful when removing the burner assembly to avoid breaking the ignitor. See Fig. 9 for the correct ignitor location. (6.) IMPORTANT: Replace screws in center panel and cells before cleaning. Insert brush end of cable in lower opening of cell, and proceed to clean 2 lower passes of cell in same manner as 2 upper passes. — — 13 /32 BURNER CELL PANEL HOT SURFACE IGNITOR ASSEMBLY IGNITOR 7 /e~ BURNER IGNITOR ASSEMBLY Fig. 9— Position of Ignitor to Burner A93347 (8.)

Any 24 -v electrical shorts during installation, service, or maintenance could cause this fuse to blow. if fuse replacement is required, use ONLY a 3 -amp fuse. The control will display code 24 when the fuse needs replacement. The control in this furnace is equipped with an LED status Tight to aid in installation, servicing, and troubleshooting. It can be viewed through the sight glass or window on the blower access door. The control indicates status with the LED on continuously, rapid flashing, or a code composed of 2 digits. (The first digit is the number of short flashes, the second is the number of longs flashes.) Refer to the service label on the blower compartment door for code explanations and useful troubleshooting suggestions. (See Fig. 13.) It is important to note that the power to the furnace must not be interrupted and the furnace blower door must not be removed until the LED status code(es) is recorded. When power to the control is interrupted, the status memory is erased. The control will store up to 5 previous codes but will not store non- current code longer than 48 hr. To retrieve previous codes, if present, no thermostat inputs to the control must be present and all time delays must expire. Remove 1 of the red main limit wires 1 to 4 sec until the LED light goes out, then reconnect it. (See Fig. 6 and 7.) (Do not leave red wire disconnected for longer periods of time as the control will assume an overtemperature condition exits and will respond with indoor blower operation.) This places the control in the status recall mode and displays the first code stored in memory. Record the code and repeat the disconnect and reconnect of the red wire, recording each code until code 11 is displayed indicating no additional faults. After the last code is displayed or after 2 minutes in the code, recall mode the control will return to normal standby mode. Use any recorded fault codes, the service label, and the trouble- shooting diagram on the following pages to diagnose and correct any problem condition. -. E. Troubleshooting Refer to the service label. (See Fig. 13.) Page 10 contains a troubleshooting guide. This guide can be a useful tool in isolating furnace operation problems. Beginning with the word "Start," answer each question and follow the appropriate arrow to the next item. The guide will help to identify the problem or failed component. After replacing any component, verify correct operation sequence.
