6300/6310 Treadmill Electronics Repair Manual – Heart Rate Possible Malfunctions 1. Strap on a Polar heart rate transmitter or hold onto the HTR handlebar. The display PULSE window shows no heart rate value. 2. The PULSE window shows the heart rate value inappropriately – when no one touches the HTR handlebar or when no one wears the Polar strap. 3. Place hands on the HTR handlebar or wear the Polar strap. The display PULSE window value differs greatly from the user’s actual heart rate.

6300/6310 Treadmill Electronics Repair Manual – Heart Rate HTR Cable/Handlebar Test Procedure A lack of continuity or a short in the wiring between the HTR board and handlebars could result in either no heart rate reading, intermittent readings, or bad heart rate readings. Follow directions below to test the 5-pin HTR cable. (1) Turn off unit power. Remove the 5-pin cable from the HTR board. (2) Set multimeter to read continuity.

If the motor is not hot, and the indicator lights, check the fuse wire and its connections. Replace the thermal fuse if wires and connections are good but the indicator lights when the motor is cool. If the motor is hot, inspect the deck and belt. Worn decks and belts produce friction, which causes the motor to draw more current and heat up.

6300/6310 Treadmill Electronics Repair Manual – Testing Emergency Stop Knob Revision Treadmills made in and after September 2004 did not have the emergency stop knob. The knob was was removed mainly because customers complained that end users didn’t know how to operate it. There were also some complaints that hitting the knob damaged it, and the knob had to be replaced too often. Permanently removing the knob on old units requires two things: a jumper and a sticker.
