smoke coming from Grundfos UP 26-99F pump
« on: November 04, 2018, 02:33:24 PM »

Am starting up the boiler for the winter and there was smoke coming from the circulation pump on the back of the boiler. Appears like its the area where the capacitor thing plugs in. Is just this part of the pump available or did something in the pump its self go bad and cause this? Play it safe and replace whole pump?

Do you have a spare pump already?  If not, buy a whole new one and install the new one and then see if you can buy replacement parts to fix the one you have now.

Am picking one up tomorrow, dealer is 2 hours away. Hope someone will know if just the part that looks melted in the pictures is replaceable and what was wrong or if something in the motor of the pump cause it to melt where it did.

Looks like they  make a terminal or thermal (called both on supplyhouse) strip kit, but don't see if for my specific pump when searching by part number on pump. https://www.supplyhouse.com/Grundfos-595424-Terminal-Strip-Kit-for-UP-Pumps
