Which unit shows the E1?
Product
E1 means
DCS RF24RE3 / RF24LE3 outdoor refrigerator
Temperature sensor fault
DCS RF24D refrigerated drawer
Compressor fault, high or low amps
Read the model plate before anything else, since one code covers two unrelated parts.
Outdoor refrigerator behaviour
When the controller concludes that its temperature sensor is not working properly, it flashes E1, lights the Alarm LED at the upper left and sounds a tone every second. A keypress quiets the tone, though only temporarily: while the fault persists, E1 stays on screen and the tone comes back for 20 seconds each hour.
Refrigerated drawer behaviour
On an RF24D the compressor is pulling either too many or too few amps. The alarm beeps six times a minute as E1 flashes. To reset, unplug the unit from its supply and plug it in once more; the manual gives no other way. A repeat calls for a technician to inspect the compressor wiring, the compressor, the control, the overload and the starter.
Owners across San Francisco and the Bay Area can read up on DCS refrigerator repair or ring (415) 969-2271. Keep the model number, the E1 reading and any power reset you attempted within reach.
Model compatibility: DCS reuses codes across series and model years, so E1 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
E1 flags a temperature sensor fault on RF24RE3 and RF24LE3 outdoor refrigerators, and a compressor fault on RF24D refrigerated drawers.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
