Alde “Red Alert Warning” for Nucamp TAB S 320 —RESOLVED!

Trekon

What should we do to correct the Red Alert Warning for our  2021 Nucamp TAB S 320 ??

Do you mean the Red Connection Failure?  Try turning off the Alde at the control panel, turn off the other appliances, too.  Then unplug the TaB from 120v.  Then go under the driver side bench, open the top of the Alde.  Remove the cable that inserts between the 2 green fuse holders.  Wait 5 minutes.  Plug the cable back into the Alde.  Plug back into shorepower.  Turn on the Alde.

Here is a picture of the 12 v cable:

Thank you, we are getting an “overheat red fail” message on the Alde screen. Do you have experience with this problem?

Overheat red fail is a fairly common Alde error.  The solution is the same:  reset the 12v power for the Alde.  Some apparently have reset the 12v by turning off the Alde control panel, then turning off the battery switch, and waiting a few minutes.  If that does not reset it, just follow the instructions in the post above.

Do you have a copy of the Alde manual?  From the Alde HE 3020 manual:

Thank you! Thank you! Thank you! I simply followed pthomas745 instructions and away went the “overheat red fail” message. Only took 5 minutes! We are now camping in Idaho with temperatures plummeting this evening. Hope to enjoy the Alde heating system this evening. Truly grateful!

Keep the thread in mind, especially the other options on the 12v cable and the pump.  May come in handy when the easy fix doesn't work!

Old thread, but wanted to add a thank you. On our third night of boondocking (also first time out with our TaB) we ran the battery dry. We hooked up to our (running) TV to recharge, but got the OVERHEAT RED FAIL error. Searching we found a lot of complicated fixes that didn’t work. Disconnecting from the TV and turning the battery switch off and back on did the trick.
