EL / EH

Furrion Refrigerator: “EL / EH”

warning RV refrigerator error codes

Safety 12V DC appliance — sustained overvoltage (EH) can damage electronics; have the RV charging/solar system inspected. Disconnect power before working on DC wiring; battery banks can arc and deliver high current.

What it means

Battery/input-voltage warnings on the 12V models: 'EL' (battery icon flashing slowly) means the DC input voltage is low (roughly 9.1–10.6V); 'EH' (battery icon flashing fast) means the input voltage is too high (above about 17V). Separately, both temperature displays showing '--' is NOT a fault — it means the fridge is in Low Power (off) mode.

Most likely causes

EL: discharged/weak house batteries or large voltage drop in the DC supply wiring most likely
EH: overvoltage from a charger/converter or solar controller fault common
'--' display: someone put the fridge into Low Power mode (held the Function button) common
Loose/corroded DC connections causing voltage to read low common

Safe checks you can do yourself

For EL: recharge the batteries (connect shore power or run the generator) and recheck.
For EH: stop charging sources and measure system voltage; if it stays above ~15-17V, have the charging system checked.
Measure DC voltage right at the fridge connector and at the battery to find any large drop (bad wiring/connection).
If the display only shows '--' with lights off, press and hold the Function button about 5 seconds to bring the fridge back out of Low Power mode.

How to reset / clear EL / EH

For '--': press and hold the Function button for ~5 seconds to toggle Low Power mode off (turn the fridge back on).
For EL/EH: correct the supply voltage (charge batteries / fix overvoltage), then the warning should clear on its own.
If needed, do a full hard reset by removing shore, battery, and solar power, then restoring it.

When to call a technician

EH overvoltage persists with charging sources off, or EL persists with fully charged, healthy batteries — the charging system or fridge board needs professional attention.

What is the most common cause of EL / EH on a Furrion Refrigerator?

The most likely cause is el: discharged/weak house batteries or large voltage drop in the dc supply wiring.

Note: EL/EH definitions are from the official FCR11DCGTA manual; voltage thresholds may vary slightly by model. The '--' = Low Power (not an error) detail is confirmed in the FCR16DCASA user manual. A common owner confusion is treating '--' as a fault when it just means the fridge was switched off.
