What is causing my Treadmill T202 to display a "connection" and make a loud beeping sound?

There could be a few potential causes for your treadmill malfunctioning. Without more information or a proper diagnosis it is hard to know for certain, but here are some possibilities:

1. Power supply issue: The continuous loud pitched tone and the lower red LED lights illuminating on the display board could indicate a problem with the power supply. This could be caused by a faulty power cord, a problem with the outlet, or an issue with the treadmill's internal power supply.
2. Control board issue: The control board is responsible for controlling the functions of the treadmill, including the programs and diagnostic modes. A malfunctioning control board could cause the treadmill to stop working correctly or prevent you from entering into program or diagnostic modes.
3. Motor controller issue: The motor controller is responsible for controlling the speed and torque of the treadmill's motor. A malfunctioning motor controller could cause the treadmill to suddenly stop running or have difficulty maintaining a steady pace.
4. Sensor issue: Treadmills have sensors that detect the speed and distance of the belt. A malfunctioning sensor could cause the treadmill to stop working or give inaccurate readings.
5. Wiring issue: There may be a problem with the wiring inside the treadmill that is causing the malfunction. This could be caused by a broken wire, a loose connection, or damage to the insulation.

It may be best to contact a qualified service technician to inspect and diagnose the issue with your treadmill. They will be able to troubleshoot the problem and make necessary repairs, or advise on replacement of certain parts if necessary. It may also be a good idea to check the warranty on your treadmill to see if it is still covered.

if the fan still turns by hand it is likely the temp sensor or power source check if there is a fuse or review a manual for location of the sensor.

1) adjust the REED switch see the diagram attached. Clean it+ 2)test for open or faulty 3) tight the connector very well.
2) tight the upper and lower connectors very well and clean it.
3) inside from console tight the ribbon cable and clean it

One of your rollers is not running true or straight causing this. Take the belt off and see if it is visibly off. Also check to see if there is an adjustment that you can do to straighten these out. This can also happen if the belt is bad and stretched. Could be just time for a new belt.

At the end of of the running belts in the end caps will adjusting bolts you will need a allen wrench to adjust the tension. Start your treadmill and turn clockwise a 1/4 turn each time see i f you can stop the belt. You need to be aware that the drive belt can also cause this problem so I suggest that you remove the motor shroud and when you are adjusting whether the front roller is moving and the running belt has stopped or the roller has stopped and motor is rotating ( adjust Drive Belt)

Normally the button and reset is in FRONT from the machine is you stand from the machine in the lower part, Is RED and at the side is reset button.

2) Test the fuse inside see the block diagram , test and replace.

3) Test the power cord for open, break
4) test the outlet wall, reset the breaker from you house, DO not use any extension cord. and proof again.
5) If you can NOT resolve the problem, you must call to the service tech,.maybe you have problem with some component, inside capacitor, transformer in the power supply.

God bless you
