The fan light switch blinks when it is time to clean the filter. Clean the filter, then press and hold the switch for 3 seconds to reset it.

I believe that's the "change or clean filter" indication. Clean the aluminum filters in the dishwasher, replace the charcoal filters if non-ducted, press the fan light over 3 seconds and it should reset.

This sounds like something has got into the track area and is setting off the safety. they are designed to stop raising or lowering if they meet any resistance and anything in the track area will cause it to happen in both directions

Hi,

Press the "Off/Clear' button to cancel anything on the display, and reset the microwave. This is a soft reset and will simply get you out of any program you have started. Press it when the cooking complete reminder appears on the display.
Perform a hard reset. Pull the plug out of the wall power supply, and wait a moment. Plug the microwave back into the wall power supply to reset any anomalies with the microwave's memory. You will need to reset the time of day if you perform a hard reset. This should help fix the problem.

It sounds like your switch is getting stuck internally. It most likely needs to be replaced.

Hope this helps you somewhat, please post back if you need more help.

I turned both the light and fan on then pushed the filter button. After a loud beep the filter light reset went off. This worked for me.

Broan model 2736A won't stay up

In my case, I pushed the button, the housing goes fully up, then right back down. I removed and disassembled the unit for cleaning. After Assembly I located two microswitches that cause the extension moror to stop at the top and at the bottom of the swing. In my case, the inertia of the motor caused the unit to "Coast" thru the top of the stroke and continue back down. I bent the outer 1/3 of the metal tabs that depress the microswitches so that the unit stopped rising a wisker sooner and no longer goes back down without pushing the button. The same coasting theroy may apply at the bottom of the stroke. The motor that runs the up and down motion is controlled by three switches, the two limit switces plus the momentary push button switch. If you don;t need to completely remove your unit for cleaning, the microswitchs can be located by removing the fan housing and looking up from inside the cabinet (under the stove) on the right side. IN my case, there was 10 years of goop to be removed.

It sounds like the fan blade may be installed upside down, or the entire motor/fan assembly is upside down. Typically, these small motors aren't reversible, so you should check the blade first.
