I have a computrainer that literally stopped working one day with symptoms where everything at the head unit appears to be correct, but when I start a warmup period (usually 6-10 minutes to facilitate roll-down calibration), as soon as I get to about 60W (measured via my quarq) the load generator clamps down HARD and I can barely turn the pedals even by standing.
The ride the evening before this failure was on zwift and was l'alpe d'huez: lots of low-cadence/high-load. I've never used a fan to cool the load generator due to ambient temps in my basement in the winter and this time was no different. Had no problems whatsoever during the session. Accidentally left it turned on overnight but with no load and not pressed against the tire.
After reading up on here, I'm wondering if it may have been a victim of overheating. And I'm wondering if anybody know what components tended to fail when a load generator overheated. Obviously racermate is no longer around to answer these questions.
I've been inside the load generator twice at this point, but only as far as removing the eddy disc. I have NOT pulled out the second board. No components show obvious signs of stress, but that doesn't mean they weren't stressed.
Hoping somebody can help me keep my LG going...
