Ariston Refrigerator Error Code rt

The rt code means the refrigerator's room temperature probe has been detected as having an open circuit or short circuit fault. This probe monitors the ambient temperature around the unit and feeds that data to the control board. The refrigerator continues to operate normally while this code is active, with probe monitoring inhibited. The error clears automatically if the probe returns to correct operation.

The rt error does not mean your refrigerator has stopped cooling. The unit continues normal operation and simply stops using the room temperature probe for its calculations. Your food should remain safely stored while you address the fault. There is no immediate safety concern associated with this error code.

Repair costs depend on what has failed. If the issue is a loose or corroded connector, the cost may be minimal, covering only your time or a small connector repair cost. Replacing the room temperature probe itself typically costs between 15 and 60 dollars for the part, plus labor if a technician is needed. A control board replacement, if ever required, would be significantly more expensive, generally ranging from 100 to 300 dollars or more for parts alone.

In many cases, yes. Start by inspecting the wiring harness and connectors leading to the room temperature probe for visible damage, looseness, or corrosion, as these are the most common causes. If the connector is clean and secure, use a multimeter to test the resistance of the probe itself to determine if the thermistor has failed. Probe and wiring repairs are generally within reach for a knowledgeable DIYer.

A manual reset is not required and may not permanently clear the code. The rt error is designed to clear automatically once the room temperature probe is functioning correctly again. If the underlying fault, such as a broken wire or failed probe, is not repaired, the code will return after any reset.
