Reading the range display

On a range or oven the fault appears on the clock or oven display, often with a beep. Press Cancel or Clear once to silence it, and write the code down first. Amana models often flash lights instead of printing text, so count the flashes.

Amana is a Whirlpool Corporation brand sold mostly through builder and value channels. Its entry-level washers, dryers and ranges use the simpler Whirlpool-family control boards, so the codes are short and often shown as flashing lights. The codes apply to model numbers such as ADB1200AWS, ADB2200AWS and NDE2330AYW; check the label on your unit to confirm yours.

What causes 4d42

How to fix it

  1. Cycle the power: turn the range or oven breaker off for one minute, switch it back on, and run the function that showed the code.
  2. Before opening any panel, switch off the breaker or unplug the appliance; this circuit can carry line voltage.
  3. Check that the doors seal and nothing keeps them from closing; look for frost build-up on the back wall of the freezer.
  4. Listen for the evaporator and condenser fans and confirm both turn freely.
  5. Unplug the unit with the doors open for several hours to melt any frost fully, then restart and watch temperatures over 24 hours.
  6. If frost returns, test the defrost heater, sensor and fans in turn and replace the one that fails; call a technician for sealed-system faults.
  7. Run a full short cycle or function again and confirm the code stays gone before putting the appliance back into normal use.

Questions

What does 4d42 mean on a Amana range or wall oven?

It is a fault code from the Amana control. It indicates a problem with the cooling system. A power reset is the first thing to try.

Can I keep using the range or wall oven while it shows 4d42?

Stop using it until it has been checked. This fault involves heat, high voltage or sealed-system parts, and running it can damage the appliance or create a safety risk.

Do I need a technician to clear 4d42?

Often yes. Part of this repair means testing live circuits or replacing a control board, so a technician is the safer choice unless you are comfortable with electrical diagnosis.
