33E relates to the ice pipe heater on Samsung refrigerators with an in-door or internal ice maker. This small heating element keeps the chute that delivers ice from freezing shut, and when the board can’t confirm it’s functioning, it displays the problem.
What Typically Goes Wrong
- A failed ice pipe heater element that no longer warms the chute
- Ice buildup inside the chute itself, jamming the mechanism the heater is meant to prevent
- A loose or corroded wiring connection to the heater
- A control board relay that isn’t sending power to the heater circuit
What You Can Check
Inspect the ice chute — the channel ice travels through from the ice maker to the dispenser — for visible ice blockage or frost buildup. If you can see ice packed into the chute, it can sometimes be cleared with a wooden spoon handle or by letting it sit with the door open briefly to melt slightly, then removing loose chunks. Avoid using metal tools that could damage the chute or your hands on sharp ice.
If the chute is clear and ice still isn’t dispensing, or the code returns after clearing an obvious blockage, the heater element itself has likely failed rather than a one-time ice jam.
When to Call a Technician
Testing the ice pipe heater’s circuit requires access behind interior panels. Our Samsung ice maker repair technicians can confirm whether the heater, its wiring, or the board relay is responsible.
