Help with freemotion incline trainer with controller comm error

[ronnygracias]

The treadmill was working fine, one day the belt snapped and after checking the unit I also noticed that the display is now showing the Controller comm error. So I opened it up and the treadmill had two boards. One is a power supply board and the other is the motor controller. I noticed there was a mouse nest, so I took power supply board out, cleaned it up, replaced the big capacitor and that did nothing. Then I took apart the motor controller and cleaned that up, and when I plugged it in, it started right up. I thought I fixed it. But when the belt arrived, I installed it and tried to power it on. It returned the same error. I tried replicating what I did, but it still shows the same error.

The treadmill is a freemotion FMTK750090. The motor controller is a cc2050 by Delta and the power supply board is a PBCL_UNI_50W by icon. Anyone knows what I could check.

The cc2050 has 6 x 820 farad capacitors that read 730-735 farad.

Any guidance on this would be greatly appreciated.

“has 6 x 820 farad capacitors that read 730-735 farad.”

This is a little bit low but it depends on where it is in the circuit if this is a problem or not

Mouse piss does quite a number on circuit boards... I would clean these boards in a ultrasonic cleaner then see what the mouse piss damaged. Its corrosive and eats everything. Been there,, done that, got the ticket and the shirt!

The 6 capacitors are on the bottom side of the motor controllers.

On it, I'll keep you'll posted and see if this fixes it.

I had to write off a whole vhf crystallized receiver because of it. Mouse pissed exactly in the tuning holes in the case. After a while the receiver quit. Looked inside and it damaged traces, damaged through holes, ate legs etc. It is as bad as a leaking capacitor. So remember where the mouse piss was, clean it with water and dawn dish soap, flowed by a pure alcohol bath and dry it off. I like the ultrasonic, as it gets into everything.
