Default Microphor electric toilet

So we are getting ready to leave on Tuesday for CO in the coach, and the toilet is acting up. It is NOT air operated, 12 v only. It works correctly, the time lets the water in for a set amount of time, but the flapper does not open. The cam seems OK, nothing appears open, but it is as if the motor has no power to open the flap.

What the deal??

Mine did the same thing?
After close inspection, the motor was working but the flapper wasn't, there is an allen key that I had to tighten. Just make sure that it gets tightened in the right spot.

I found that I have power to the 2 wires going to the motor when the toilet is flushed, but the motor does not appear to be turning. I tried feeling the motor and what appears to be the shaft that goes through the ecentric plastic piece, and don't feel any motion. I'm wondering if the motor is bad? Also wonder what the 2 purple wires are that are near the round disc that turns the flapper?

Adam - my Microphor is a model LF-220 and according to the manual the two violet wires go to the limit switch on the motor cam. Hope this helps.

From what I've found tonight, it appears the motor is getting power, but not turning. I removed the linkage, but can not turn the motor/wheel assembly. It looks like a awful tight place to work to get the motor out without removing the toilet.

Removing the toliet is not that bad of a job. Get a new wax seal and pull it. You might be able to match the motor somewhere local but if your going to pull it I would get a rebuild kit and do it all at once.

About a month ago I had the same problem with my motor. Power, but it didn't run.
I removed the motor without removing the toilet. If you remove the cam you can access the screws that hold the motor and gear housing to the plate on the hopper assembly.
You will need a 90 degree screwdriver to get to the screws. After I removed the motor I applied 12v and verified that it was indeed the motor. The new motor is pricey. I took the motor apart and found that one of the springs that puts pressure on the brush had dissentegrated. I made a new one using a ball point pen spring, put it together and it worked. Not that hard and saved some cash.
