If recently lubricated, it doesn't need it again.
The belt tension, though, could be the problem. Adjust it, by all means.
(When you applied the lubricant, did you spread it around evenly on the belt, and did you use non-grease lubricant specifically meant for treadmill belts? that is vitally necessary and required for good results.)
It's simple: if it slips when you run on it, it is too loose. Tighten it a little from there, and it will be about right.
If the belt is kept adjusted too tightly, it will wear out.
Is the belt frayed at the edges anywhere?
I think your 'true' tech may have perhaps not been quite telling the truth in that case.
But this problem puzzles me a bit, so I think another Expert should look at it... so I have Opted Out, opening the case to other Experts in this category, at no additional charge to you.
I will still be able to see, and respond, to any further postings to this case, or post again if I have more ideas.
Hi different expert here.
I have worked on these for many years and with this kind of problem you really need an expert to look at this one. The problem could be one of many and it would cost more to just blindly begin replacing parts you don't need;-)
They will get you going faster and with less grief and cash outlay.
I wish I have better news but thats what I would do myself if faced with something like this.
At least the original owner seems to have been honest with you.
Lol, we will see.
If you need help locating someone near you you can always contact Sears, they have such a service local to anyone in the US;-)
And they are fair and honest.
Please rate my service to you kindly before you go, and that way I can stick with you until this if solved. I will help you anyway I can.
After you rate, you can then contact me any time by simply replying to this message.
Have a great day and best of luck with this unit;-)
I can tell you it is a good quality machine.
Hi, this could be and sounds like a unit in need of a service call.
The reason is that When you made that change by loosening the belt you get the error E2:CAL.
That means this may need a speed sensor or possibly other parts are out of alignment. Its something you could do but it would be much quicker to simply have a tech come do this for you. Sears offers a home service for this and they are really good and fair priced. I used to work for them as a home service technician.
You could try replacing the speed sensor which is easy to do as well and I will help you if you decide to fix this yourself then we would do a new Calibration and that likely will fix this. The part is pretty cheap as well.
The best place to get that would be Treadmill Doctor:

If you rate kindly at this time, you and I will be together until you are finished with this repair, simply rate, then when you have the part or any other question about this Treadmill just reply to this message, there is no additional cost to rate me.
Thank you and have a wonderful day!Tech Michael
Hi good morning ,
in most cases I have seen this would be the sensor. But if I were you I would replace both those components to be sure you dont have any issues down the road.
The sensor can get weak and cause thas just as much as the board you metioned. I would get them both.
Both are very easy to replace, no soldering. When you are ready to do this, first tke a few pics of the board to be sure where the wiring clips plug into the board;-)
You will have no trouble with this part.
Once the board is installed and the sensor replaced the same way, I will help you calibrate the unit to work perfectly.
Please don't jump ahead on this, before you do anything ask me so I can be sure you wont have any negative issues;-)
Please Rate my service to you kindly at this time. It will ensure we don't get separated. ALso there is no cost to rate, but you can then reach me anytime until this task is complete.
