Macerator doesn't - just quit.

Went to drain the tanks and nothing happened. (No clicks, no thumps, no start and stops) Replaced the relay in the wet bay; no luck. Crawled into the passenger bay side and checked the mini breaker. Continuity between posts, voltage when measured using the ground. Finally got the wires off the back of the switch and there is power there too. When I tested the switch; it worked, but the pins on the back were bad and so I'm ordering a new switch. From my viewpoint, it appear there is power all the way to the unit, but it doesn't start. I back flushed the macerator and then partly filled the black tank. It drains even though the macerator is not on. (Siphon or gravity pressure). Finally, I cannot hear the relay click, cannot feel it click/work so now I'm baffled.

Anyone have any other tips or tricks to check for the problem? I'm really concerned that there might be another fuse somewhere that I am not seeing in the bay or on the macerator itself. I have not removed the top of the unit box.

There may be a small rubber cap on the motor end of the pump. Under that is a slotted shaft, used to rotate the pump with a screwdriver.

Pump may be stuck, try turning it a few turns both ways.

There is nothing inside the box except for the pump/motor. Only way to get to the motor is either remove the macerator or cut a 5 in hole in the wet bay floor, which I wouldnít recommend. I had to replace my macerator due to leak and when I went to disconnect the wires the power wire came apart so it had a bad crimp. You might check the wiring going into the macerator back upper right hand corner.

The most common problem with the macerator reported here on iRV2 is simply that someone managed to throw something down the toilet (a wet nap, a towlette, a "wipe") and that non-standard object has jammed the macerator. That is a very common problem and is usually resolved just by taking the macerator unit apart and servicing the unit (not a task most of us want to tackle). A recent thread up here with a similar failure of the macerator elicited a lot of suggestions to either find the slot in the top of the shaft that is the same shaft of the macerator impeller and manually turn the shaft counterclockwise (or clockwise, whatever works) to try to dislodge the "wipe" or object that might be there, or one fellow fixed his problem by having someone "backflush" the system to remove a wad of toilet paper or other material. I don't think that you have tried to dislodge a possible object.... have you? Why are you convinced that it is an electrical problem? If the blades of the macerator are jammed solidly, I doubt that you would hear any click or anything other than the sound of a motor trying to turn which cant (hummmm).
