E22F28302 Genuine Line Flow Fan for Mitsubishi Electric Split System Air Conditioners, Indoor Unit Cross Flow Fan Barrel

E22F28302 is a genuine Mitsubishi Electric line flow fan, the long barrel shaped fan inside the indoor unit of a split system. Some people call it a cross flow or squirrel cage fan. Fans are made to suit the length of each indoor unit, so the part number matters. Models aren't linked to this fan in our records, so check it against your indoor unit's parts list before ordering.

Noisy indoor unit or weak airflow

The line flow fan runs almost the full width of the indoor unit, drawing room air through the filter and coil and pushing it out past the vanes. Dust and mould can build up between the blades over the years, and a damaged or dirty fan soon falls out of balance. Signs include a rumbling, ticking or whirring noise, vibration through the unit, weaker airflow than it used to have, and musty smells. A fan with cracked or missing blades will keep vibrating and can damage the motor or end bearing if left running.

Replacing the line flow fan

Isolate the air conditioner at its isolator or circuit breaker first. Getting the fan out usually means removing the front cover, the vanes and the drain pan, then releasing the fan from the motor shaft and its end bearing. Check the bearing and fit a new one if it's worn. Because the coil and drain pan are disturbed, this is a job for a qualified air conditioning technician.

Questions about this part

Can the old fan be cleaned instead of replaced?

If the blades are intact and the noise comes from dirt or mould, a professional clean may fix it. A fan with cracked or broken blades, or one that wobbles on the shaft, should be replaced as it will stay out of balance.
