L2250 air flow light on

[Stevek]

Hi folks,

I'm new to the forum, so forgive me if this question seems simplistic.

I have a L2250 that has the air flow light illuminated. The light is actually described as the "alarm for when the air filter is clogged". I had not started the tractor all winter, but it was stored in a dry environment and had the battery removed. When I started it this spring the light was illuminated. I've replaced the filter, but the light is still on. The tractor seems to work fine, but the light remains on.From what I can tell, the air cleaner sensor is on the right side of the tractor just above the battery and is screwed into the air intake tube.

Can anyone tell me if this is indeed the air intake sensor and if so, can it be tested before I spend money replacing it?:

Are you sure there are no "nests" inside the tube? You would be surprised as to what a small rodent can do!

Sensor might be bad too.

That sensor is not a cheap part, about $100 shipped.

Here is how you check it.

That’s the only time mine has come on was when something hid acorns throughout the tube and filter housing
