Kenmore Refrigerator Error Code Er dH: Meaning and Fix
Reading the refrigerator display
On a refrigerator the code shows on the control panel or dispenser display. Some models flash a letter or alternate two characters; hold the code in view and note both. Check the model-number prefix first: the same Kenmore code can mean different things depending on the manufacturer.
Kenmore is a private label, and the factory that built your unit decides which fault codes it shows. The first digits of a Kenmore model number (110, 417, 665, 795, 796 and so on) tell you whether Whirlpool, LG, Electrolux or Frigidaire made it. Check the model label on your unit before using any chart.
What causes Er dH
- A burned-out heating element or open thermal fuse
- Open defrost thermostat
- A damaged wire, connector or relay on the control board feeding the heater
- A faulty temperature sensor (NTC) reporting the wrong reading to the control
How to fix it
- Switch the appliance off at the breaker and let it cool completely before working on it.
- Inspect the heater wiring and connectors for scorching, looseness or corrosion and reseat them.
- Test the defrost thermostat and heater.
- Test the heating element and the temperature sensor for continuity/resistance with a multimeter against the values in your service sheet.
- Replace whichever component fails the test; never bypass a thermal fuse.
- Reassemble, restore power and run a hot cycle, checking that the water or air reaches temperature in a normal time.

Questions
What does error Er dH mean on a Kenmore refrigerator?
The defrost heater is open or not heating. Kenmore sells units built by several manufacturers, so the code table that applies depends on who made your model; use the model number to confirm.
Can I keep using my refrigerator while Er dH is showing?
You can run cold or short cycles in a pinch, but results will be poor, and a heater that stays on is a safety concern, so repair it soon.
How do I clear Er dH, and can I fix it myself?
Cancel the program, switch the appliance off and leave it unplugged (or the breaker off) for about five minutes, then restart. The code only stays cleared if the underlying problem is fixed, so work through the steps above. Parts here involve electronics, heating or sealed components, so consider a qualified technician if the basic checks do not clear it.
