INCLINE ADJUSTMENT ISN'T WORKING

Please RUN the software caibration for diagnose, troubleshooitng, and fix it Maybe you have speed sensor faulty or bad adjustment, clean it and tight wires connector.
God bless you

1) readjust the speed sensor, clean it and tight the wires connector well
2) see the block diagram.
3) RUN the software calibration for diagnose, troubleshooting , fix it
4) lube the gear and shift elevation motor.
5) adjust the POT, a little and see if you have a better improve.
6) see the diagram, and proceed
God bless you

If you have a spark, you don't have a "Magneto" problem, Check the air filter and the 2 stoke oil tank. And check that the spark plug is wet, if it isn't firing and the plug isn't wet, you don't have any fuel getting to the combustion chamber.

RUN THE SOFTWARE CALIBRATION FOR DIAGNOSE, TROUBLESHOOTING AND FIX IT.

2) you can lube the gear, shaft+ adjust the potentiometer+see the relais contact are clean it.

sincerely. God bless you

First, you shouldn't adjust the idle. If the idle isn't correct, that means there is an issue somewhere - not that the idle needs to be adjusted.

There isn't an adjustment screw. To adjust the idle, you will need to move the TPS (Throttle Position Sensor) forwards or backward. To do this, you will need to remove the tamper proof bolt and replace it with one that can be loosened and tightened.

Dear Sir:

I STRONG recommend RUN the calibration Software Inmediately, for eay Diagnose and troubleshooting, most of them instruction has coming in the Hood of Motor, follow the instruction or use your instruction manual.

Adjust the sensor speed attached the diagram. Tight the wires from sensor speed. The sensor speed can be faulty. Adjust the Pot with the gear in the same motor, both can be faulty. And finally the main motor board can be wrong. sincerely.

God bless you.

It sounds like you have a membrane issue. There are a number of different T9450 models and they all have slightly different consoles. You'll need your serial number to help pinpoint the parts you need. Your best bet is to go through the manufacturer (johnsonfit.com) and have them help you get the correct membrane and overlay.

Double check that all connections are secure, especially the console cable. Unplug and reconnect the console cable to verify.
Unplug treadmill from wall outlet. Wait 60 seconds, allowing lower board to discharge built-up energy.
Remove motor cover.
Verify that there are no lights lit on the lower circuit board.
Verify that all wires are securely and correctly placed on the lower circuit board, especially the large wire harness on the top of the circuit board with 12 different colored wires coming out of it.

Good, I'm glad that is all it was.

Make sure your coolant level is full.
Does the temp guage stay just to the left of middle when idling??
I have a feeling your t-stat is sticking and at idle the motor isn't making enough heat to keep warm with the t-stat sticking open. you've got a coolant problem. I'm more inclined to believe its low coolant level rather than the thermostat - especially if the CEL light isn't on. If you don't find an obvious leak, pull the oil cap and look on the bottom of the cap. If you find a butterscotch colored sludge, you probably have a head gasket issue. A shop can pressure test the system and determine what is the most likely cause.
