Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I don't think maintenance will help with the resistance feature not working.
But, what is the problem?
And, is there any error code showing on the console at any time?
Resistance failures are either
1. operator error
2. defective console (unlikely)
3. defective resistance motor controller board
4. defective resistance motor
5. defective linkage (unlikely).
Let me know more about the problem, please.
Coarse-grade resistance adjustments, when there are any at all, is the idea I get from your description of the problem.
Was the gradual resistance, and its working along with the mapped grades, formerly working?
Where was the bike stored in the interval of disuse?
And in what temperature/humidity conditions, and was the place dusty at all?
Good. That means it wasn't a change owing to extremes in the storage environment.
Would you be willing to try a reset of the console (if I can find a procedure for one) that might erase your personal settings, but would set things back to factory condition?
I know this is not a profound query about the problem, but it has to be asked:
- is the machine less than a year old? or less than 2 years old? measured from purchase date.
Then it is out of warranty. Repairs would be at your own expense.
It was well that you tried the console reset. But that and other reasonable things to try, has had no result.
The one last thing to try is calibrating the incline.
I have no further ideas on this case (except 'call a repair person' - and if you need a guide to which repair professionals in your region would be competent to work on this type of machine and problem, please let me know your zip code.)
So I have Opted Out of the case, not cutting off communication, but opening it to other Experts in this category in case one takes it up and has more to offer.
