I have 2 of these here that quit working within a month of each other. The controllers still light up and will go thru functions, but pumps don't spin. Impellers still look like new, no bulging on magnets. Does anyone know what is the common failure on these? Is the anywhere to get replacement parts? Tia
 
Any idea what it is that fails? They have already been replaced with mp40's. Just seemed like a waste to just toss them if they could be saved. Looks like that's where they're headed. Thanks
 
There is a small ceramic ring on either side of the impeller that actually seizes up and creates too much friction between the impeller shaft and the pump housing. The fix is to cut a piece of standard airline tubing the same length of the rings and just replace them with the tubing. Several write ups on Reef Central. The other issue is power supplies, they use very very cheap power supplies that tend to overheat internally and die. Cheap fix is to get another one from Amazon, more expensive and long term fix is to get a single mean well power supply and run ALL of your 24v jebao pumps/powerheads off the one power supply.
