Overheat Red Fail

jpi68 · September 2019

We pulled into our campground tonight and turned on the Alde system. Immediately got an “Overheat Red Fail”. Read in the manual to check the glycol level, bleed the lines... Have no idea what they are talking about... Can any one help...

Check out my Sep-07 comment on the above thread.

Disconnecting +12VDC seems to clear false error.

Thank you #MuttonChops, worked like a charm.... Checked my glycol level and it was fine. Unplugged from shore power and killed the battery switch for about 15 seconds... The warning stopped and I can hear the alde system kicking in. Good thing because its about 40 degrees outside and the cabin is a little chilly... Thanks again..

Score one for the forum wisdom again!

Got the Overheat Red Fail when I turned the Aldi on at campsite. Fix worked like a charm. Thank you!

For a preventive fix, I installed Kill switches on the DC power lines to both the Alde & Jensen..

So these two devices are never consuming power while turned off at the device, and these kill switches remain off unless we need to use the device. Their blue light also reminds us to turn them off to avoid the problem discussed above (caused sometimes by not turning off the Alde before cutting power).
