Analysis
From the IA52 command compare LRATE (-0.282) with AVLRTE (0.017). This shows that there is excessive
compensation. The most likely cause for excessive compensation is a false probe temperature reading. Examining
the IA52 command did not show erroneous thermistor values. However, examining the IA51 command showed
that the board temperature value was intermittently bad.
Solution
Replace probe and delete rate table.
Intermittent bad values.
Yet probe’s temperature
readings look good at
this time!
