  If your air conditioner isn't operating correctly, consider these potential solutions: * Ensure that the input voltage is within the specified range (rating voltage ±10%). * Verify that the indoor and outdoor units are correctly connected with the same number of cables. * If in HEAT mode, the compressor and indoor fan might stop intermittently if the room temperature exceeds the set temperature. * In HEAT mode, the compressor may run in reverse to defrost external ice, causing temporary stops of the indoor and outdoor fans. * The compressor may stop intermittently, or the indoor fan speed may decrease to prevent freezing, depending on the inside and outside air temperatures. * Check if the timer is activated; if so, cancel the timer operation.

  If only the timer LED is lit and the air conditioner isn't working, the timer function may be activated, placing the unit in ready mode. To resolve this, cancel the timer operation, and the unit should operate normally.

Why do the indoor and outdoor fans on my Samsung UQ18A9RE Air Conditioner stop intermittently in HEAT mode?

  In HEAT mode, the compressor operates in a reverse cycle to remove ice from the exterior. During this process, the indoor and outdoor fans may stop intermittently, but this should not exceed 20% of the total heating operation time.
