Norcold N8DC and N10DC 3 Flashes: Compressor Won’t Start

3 FLASHES

Norcold N8DC and N10DC 3 Flashes: Compressor Won’t Start

The compressor tried to start and couldn’t. Either the rotor is stuck or the pressure difference in the sealing system is too high (over 5 bar). The module gives up after 3 start attempts.

Before you start

  • Pull it out first. Most tests need the fridge slid out of its enclosure with 12V still connected.
  • Most common cause: turning the fridge back on too soon. The pressures need about 5 minutes to equalize.

Fits these models

N8DCN8DCXN10DCN10DCX

Norcold’s 12V DC compressor refrigerators (8.2 and 9.7 cu ft). These run on 12 volts only: no propane, no 120V heater.

How to read this code

3 flashes, then a pause. This code comes from the compressor power module, not the front panel. You read it with a test LED.

  1. Pull the fridge out of its enclosure, but keep 12V connected.
  2. Take the 12V input wire off the module’s + terminal and fit a 1/4″ piggyback adapter on that terminal.
  3. Connect a 10 mA LED: red lead to the adapter, black lead to terminal D.
  4. Plug the 12V wire onto the adapter’s other tab. Count the flashes (each is 1/4 second), then the pause, then it repeats.

Write down every code, then remove the LED and adapter. Don’t leave them in for normal use.

STEP 1

Let the pressures equalize

Turn the fridge OFF for at least 5 minutes, then turn it back ON.

Does the 3-flash code come back?

NO

Problem solved

It was just restarted too soon. Wait 5 minutes after turning it off before turning it back on.

YES

The refrigerator needs replacing

The compressor is stuck or the sealed system is faulty. The fault is in the sealed cooling system or compressor, which isn’t serviced in the field. Ask a tech about your replacement options.
