Question about Nordic Track NordicTrack C2300 Treadmill

Open Question

Treadmill Starts very fast and then shuts down

Hopefully someone can help me with finding a solution to this problem. When I start the treadmill (At any speed) the motor fires up rapidly and fast (Sounds like it's going at 110%) then it trips the safety and cuts the power to itself. I then have to turn the on/off switch back to the "on" position and try again... but when I try to turn the treadmill on again it does the same thing. Starts up very fast and then trips the safety. Other info - it trips within 1-2 seconds. when the treadmill turns on you can see the lights dim like it's drawing too much power.

SOURCE: My Nordic Track treadmill has has 10 speeds (1mph

You should have a speed arrow up & down, this increases and decreases the speed in .1 mph. Try this control and see how the unit re-acts if the speed does not adjust in .1 mph increments or it stay the same either way it sounds like an upper board issue. Go to go to customer service the replacement parts put you M# and will give part# and pricing.

SOURCE: Nordic Track treadmill trips GFI.

Have you lubricated the the running deck? The lack of lubrication can increase friction thus causing the GFI to trip. simple test start the treadmill do not walk on a see if the GFI is tripped in it does trip then lubricate, then if after lubricate it still the you have a worn belt and possibly damaged deck depending replacement price and on what you paid for the treadmill it may or may not be worth fixing.

SOURCE: My C2255 will start rotating

If the console works fine then it's a controller malfunction, yes. The microcontroller responsible with the voltage regulation for the motor is not working properly so that needs to be replaced. Unfortunately, you can't change only that module since it's welded in the mainboard.

SOURCE: Belt on Nordic Track T4.0 treadmill stops

Dear Sir:
1) Lube the treadmill in according with the instruction manual.
2) The reason is lack of lube by maintenance, that produce enough friction with shut down for to protect electronic system.
3) Test the deck belt if is worn, and replace it.
4) Test the rollers bearings
5) See the bearing motor
6) Test the input voltage motor coming from the output from the main motor board,, use DVOM.
7) See my personal TIPS for HELP.

sincerely. God bless you

How can I slow down a Sportcraft TX 320 treadmill?

Hi There, hmmm.... am I hearing that the treadmill starts too fast? At over 1mph? Most US treads will start at 1MPH and some will allow selection of .5MPH in the maintenance mode settings maybe. Otherwise, this could be attacked by a technical crew, like jatinah electronics possibly. If the treadmill would be set at one speed only that could be accomplished by reducing the drive signal at the component-level. It is certainly workable, but I would need to know what the current speed is that is too fast for her, and her ideal speed. ;o)

Technofit ts500I treadmill When its running the treadmill starts and runs fine. However when I get on it, it the speed becomes jerky running slow fast slow fast making it impossible to use.

If someone spilled a drink on the belt, it will become sticky as it dries. The belt will try to stick to the bed of the treadmill. Loosen belt, wipe clean the bed, underside of belt, and end rollers.

Two lines appear on the console screen and incline starts going up, then when key is removed all lights go on but nothing works.

I assume you are talking about the safety key. It should have a string attached to it and a clip on the other end of the key's string.

The key is a safety feature and the key should be in the control panel and the clip attached to your shorts or shirt when you are using the treadmill. If you fall of the treadmill, the clip pulls the string and the key is pulled from the panel on the treadmill. This should stop the treadmill instantly by cutting main power to the unit. Main power is shut off because the key is a safety device and it MUST work every time. To help avoid design errors or unreliable stops when the key is pulled, a good designer will shut everything off, not just the motor for the tread belt. I would say your unit was designed by a good design team since everthing goes off when the key is pulled.

From my point of view, it is working as designed unless you are talking about a different key.

I know someone who did not wear their safety key and they slipped on the treadmill, the treadmill threw them into the wall behind the unit and they were stuck with their leg against the treadmill. The belt on the treadmill wore their skin down to the bone on their knee in only a few seconds. Lesson one, keep your treadmill at least 3 feet from the wall. Lesson 2, use the safety key and clip.

My Proform XP 650e Treadmill starts and suddenly stops. The belt turns real fast then it suddenly shuts down like the power was turned off.

This condition is when the treadmill goes to full speed as soon as you power up the treadmill. Typically when this occurs, it is an indication of a short circuit in the motor controller.
