I had to replace the rotary inductor twice in my MFJ-989C because it was
intermittent , not as a result of dirt or corrosion, but that the inductor
had warped from heat. I had used it to tune a short 160 meter antenna. It
is a T tuner, not an L tuner. T Tuners can lose up to 25% of power in heat
at 1.8 MHz. So, I was dissipating 250 watts in heat inside the tuner box. I
could feel the warmth by touching the cabinet.
Hopefully, this is not your problem.
Best Regards
Dan Schaaf

I've used DeoxIT from CAIG Laboratory with good success. It's available on
Amazon and other sites and is available in a number of application formats
(e.g., spray, dropper, pads, etc.)
