I have a Trimline Model T325/T335HR treadmill that stopped running about half way through my workout today. I get an ERR1 message on the screen & resetting the unit by unplugging, pressing the safety button in & plugging the unit back in worked a couple of times, but only for a few minutes and then the machine would stop running again. Now it won't start at all. The manual gives no clue what to do next. Can you help? I should also mention that just before it quits running, the unit makes a funny gravelly type of noise, but the unit shuts off before I can identify where it's coming from.
Resetting the unit by unplugging the power cord and then plugging. back in.
Hi, I’m a moderator for this topic and I wonder whether you’re still waiting for an answer. If you are, please let me know and I will do my best to find a Professional to assist you right away. If not, feel free to let me know and I will cancel this question for you. Thank you!
Yes I am still waiting. So far no one has responded.
A treadmill will shut down/slow down from too much friction which is due to high motor current because the walkbelt and deck are not properly lubricated. Take an amperage reading from the motor and if it is above 10-12 amps steadily I would recommend lubricating the deck first and retest if it still cuts out replace the controller and finally,After replacing the controller and lubricating take an amperage reading from the motor and if it is above 10-12 amps steadily replace the walking deck because it is worn out. Apply .5 oz of lubricant on the deck every 3-6 months or 100 hours of use. This will extend your treadmill's life many years.If the unit will no longer turn on try the following steps to diagnose:Check to see if the breaker has tripped in your house or on the unit itself(should be part of the on/off switch or separate close to the power cord). If nothing is tripped open the motor cover and look to see if there are any LED'S lit on the electronic board (motor controller). If there are no lights lit check with a volt meter to see if there is 120 volts coming into the controller. If there is and no lights are lit then the controller is bad. If there isn't 120 volts into the controller, check your outlet and cord, then finally check the on/off switch for proper operation (and if your unit has a power board make sure there is power into and out of it).If the controller is lit up and the console is dead you will need to check for continuity in the harness between the controller and the console. Check for power into the console from the controller. It should be around 9-12 vdc and that is usually read between the red and black wires in the harness with the safety key on. If it has voltage in and doesn't light check the safety switch for proper operation. If it is ok replace the console.If there is no voltage into the console double check the wiring and possible loose connections, then if nothing is found replace the controller.
The controller is lit and the console is not dead. It doesn't seem to be a power problem & the deck has been lubricated. Any other ideas?
ou will need to check the speed sensor for proper alignment, cleanliness and function. it should be located near the front roller or mounted on the motor. It should be within a credit cards width of the magnet or 3 credit cards width of the toothed wheel. You can test these manually by turning the wlak belt by hand and look to see if there is a blinking LED light on the motor control board. If there is the sensor is working and if there isn't the sensor needs replaced.
None of those are the issue. Sorry, you didn't help at all.
Then ultimately this is the last thing to tryTest the amperage draw through the red motor wire when you are wlaking on the treadmill at 3mph. If it is over 12 amps replace the walking deck and controller. If it is under 12 amps replace just the controller. You can use a clamp on meter to test the amperage. They are available for purchase at Lowes.
