Re: Treadmill automatically speeds up upon start up
If you have a unit where the speed can be adjusted with 1 mph increments 0 to 10 and with speed up or down .1 mph increments . it sound like the key pad itself is causing this problem. Depending on manufacturer you can purchase the keypad/overlay and some will want you to purchase the entire display.

1) Run the software calibration for easy diagnose, troubleshooting, and fix it. 2) You must adjut the speed sensor, clean and tight the wire connector. God bless you.
Press the Stop and the Speed Up keys down while inserting the safety key. This should get you into calibration mode. Press the Stop key one time. The Time window should read EP:2P. Some newer models may also say FP, Pass, or the like. This means that it passes the EPROM test. If you cannot get into calibration or if the EPROM test fails then the upper console will have to be replaced. If you get pass to this point then proceed with the calibrating the incline and speed. Press either incline key and the incline will calibrate automatically. Be careful the treadmill will run at full speed in the next mode DO NOT STAND ON THE WALKING BELT.Press the Speed Up key and hold it down until 85 is shown in the Distance window (some models may show the 85 number in another window). If the top speed of the treadmill does not match the displayed speed on the computer console, adjust the max speed potentiometer (pot) on the motor control board. This is the board that the red and black motor wires connect directly into in the motor area. The Max Speed pot is clearly labeled The max speed potentiometer is a small square with a mobile center and is located in one corner of the board and is labeled MAX SPD. It is near the harness that carries the speed signal labeled H,W,L. Using a small insulated screwdriver adjust this potentiometer clockwise to speed up and counter-clockwise to slow down the max speed of the treadmill. A tiny turn of this potentiometer will make a big difference in speed so be careful when making adjustments. It is not important to get the speed set exactly at the max speed of the treadmill but do make sure to get the speed within .2 MPH of the max speed of the treadmill. For instance if the max speed of the treadmill is 10 MPH, make sure to have the speed set between 9.8 MPH and 10.2 MPH. Some models have a 12 MPH top speed, so please check your manual if you aren’t sure. After completing calibration of the speed, press the Speed Down key. The treadmill will automatically return to 0 MPH. Please allow the unit to stop completely before continuing.Press the Stop key once and remove the safety key.

E21 means the treadmill is not picking up a speed signal once the start key is pressed. First, determine if the motor is turning before you get the E21 or not. If the motor turns, the speed sensor is the most likely problem. If it does not, you can manually turn the belt with your feet before you get the E21 and you should get a speed reading but eventually you will get an error code because it is almost impossible to keep the speed constant enough for the computer. Try running it through calibration with the motor shroud off.

The max speed potentiometer is a small black square with a white center and is located near the three small speed wire connections labeled H, W, & L. Using a small insulated screwdriver adjust this potentiometer clockwise to speed up and counter-clockwise to slow
down the max speed of the treadmill. A tiny turn of this potentiometer will make a big difference in speed so be careful when making adjustments.

If the motor does not run, test the motor but first unplug unit then unplug the two leads ( Red and Black ) that is connected to the Motor Control Board.Cordless drill battery- get a fully-charged, 18 volt (preferred) cordless drill battery and on most treadmills connect the red and black motor leads to the battery (some have different colors but if you have two wires and get it hooked up backwards, the motor will just run backwards and won’t be harmed). If good, the motor should operate at about 1 MPH. Then Motor Control Motor will need to replaced
That treadmill has to be calibrated upon replacement of controller. Contact the place were you bougth controller and request calibration procedure. Hope this helps.
when I start the treadmill the speed goes up on its own even when the setting is on manual. I had the unit for a few yrs, but just started to do that recently.
