The coil could be the problem, but can you give us some background on the machine, have you had it awhile, is it new to you?

What have you checked to bring you to this conclusion?

What kind of maintenance have or do you preform on this machine?

Is this a machine that sat for a long time and has recently come out of storage?

Anything that you can tell us about the machine could be helpful in diagnosing the problem.
