What Er dH means

On Kenmore 795. refrigerators, an LG-built platform, a dH message belongs to the defrost system. The documented wording on this platform is F dH or r dH rather than Er dH, so the front letters may differ from what you read. In every form it means the defrost sensor did not climb above 40 degrees F during a defrost cycle. You may see frost building on the back wall of the freezer, rising temperatures, or ice around the evaporator area.

Common causes of Er dH

Defrost heater not warming
Defrost fuse or thermal link open
Defrost sensor reading wrong
Main control board

✓ One safe check you can try

1. Check the freezer for frost on the back wall and food that feels warm. 2. Keep the doors shut and avoid opening them often. 3. Move perishables to a cooler if the temperature is climbing. 4. Do not chip or scrape ice, and do not use a hair dryer or heater inside. 5. If the code stays, call us and say whether it reads Er dH, F dH, or r dH.

! Why to stop there

A defrost problem can be a heater, a fuse, a sensor, or the board
We check what is likely in sequence, starting with the simplest
We quote in writing before replacing anything

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Er dHEr dH questions

Is Er dH the same as F dH?

They point to the same defrost sensor condition on this 795 platform. The documented forms are F dH and r dH, so we ask exactly what you see and confirm it ourselves.

Why does frost matter?

If the defrost heater does not warm the evaporator, frost builds and blocks airflow. The refrigerator then cools poorly even though the compressor keeps running, and food can warm.

What is checked in a defrost repair?

We test the defrost heater, fuse, and sensor in order and look at how the control runs the cycle. You get the findings explained, a written price first, and a 30-day warranty on our workmanship.
