What the 296 error code actually means

Your Samsung air conditioner has detected a problem with the sensor that monitors refrigerant pressure on the low side of the system. The sensor is either sending a signal that is too low, indicating a short circuit, or no signal at all, indicating a broken connection. The unit has stopped normal operation to protect the compressor until the issue is resolved.

Questions people ask about 296

What does 296 mean on a Samsung air_conditioner?
Error code 296 on a Samsung air conditioner indicates a low pressure sensor circuit fault. The control board detected that the sensor signal voltage was either below 0.4V, indicating a short circuit, or above 4.2V, indicating an open circuit. The unit stops operation to protect the compressor until the fault is corrected.
Is it safe to keep running my Samsung AC with error code 296 active?
No, it is not recommended to attempt to bypass or ignore error 296. The low pressure sensor protects the compressor from running under unsafe refrigerant conditions. Operating the unit with this fault active risks serious compressor damage, which is a significantly more expensive repair than resolving the sensor circuit issue.
How much does it cost to repair error code 296 on a Samsung air conditioner?
Repair costs vary depending on the cause. If only a connector needs to be cleaned and reseated, costs may be limited to a service call fee, typically in the range of $75 to $150. If the low pressure sensor needs replacement, parts and labor combined can range from $150 to $400 or more, depending on the unit model and local labor rates.
Can I fix error code 296 myself?
Some causes of error 296 are accessible to a knowledgeable DIYer, such as inspecting and reseating connectors or checking for visibly damaged wiring. However, testing sensor output voltage requires a multimeter and some electrical knowledge, and any work involving refrigerant or internal system components should be handled by a certified technician.
Will resetting the unit clear error code 296?
A simple power reset will not permanently clear error code 296 if the underlying wiring or sensor fault still exists. The error will return as soon as the unit attempts to operate and the control board reads the out-of-range voltage again. The root cause in the sensor circuit must be repaired before the code will stay clear.
