Default E-3 error code-Link 2000

Recently, while dry camping, I developed a flashing E-3 error code on the display panel of my link 2000 while the generator was recharging the house batteries thru the Heart 2500 Inverter/130 Amp Charger. The book describes this code as an "inverter or charger over temp shutdown". Outside air temperature was in the high 80's-low 90's.This condition repeated itself several times over the course of 4 days. The condition does not exist when charging by shore power or while driving.

Any ideas?

From your description, the E-3 "over-temp" fault code is probably accurate, with the Freedom 25 inverter/charger automatically protecting itself against damage from overheating. Finding the proper location for the inverter/charger involves a compromise. To provide cooling to minimize or preclude E-3 shutdown incidents during hot weather operation, the inverter/charger could be located in an air conditioned space within the interior of the coach. However, this is "prime real estate." In addition, the inverter/charger often makes some noise, buzzing as it charges or inverts. Newell has chosen to locate the inverter/charger in an exterior storage compartment, realizing that this may occasionally result in an overtemp shutdown. However, Newell believes that few owners would want this component installed inside the coach. The reason that you have experienced the problem while operating the generator but not on shore power is that the generator radiator exhausts hot air under the coach, warming the compartments from below. One issue to check: make sure that miscellaneous items are not packed too tightly around the inverter/charger. The unit needs to freely ventilate.

I had the same problem, so I added a small blower fan aimed at the unit that comes on with the generator fan. One caution, if you experience too many over temp shutdowns, the unit will stop resetting itself. jc
