Just what we needed

Great hose replacement for our pellet stove


Ordered low limit switch and hose and it fixed my stove. Parts arrived on time and worked as advertised

Randy C.
Great Service

My order was complete and shipped free and on-time as promised. I received the order in three days via USPS, it came from the East coast to my Colorado location. The only problem I encountered was the terminal ends on the igniter were opposite of what I needed, I cut them off and replaced them with the correct ends and they worked fine. The igniter was ordered using manufacturer's part number from the USSC manual that came with the stove. I was somewhat disappointed that the terminals had to be cut and replaced in the field. Also, I ordered replacement high-temp silicone vacuum hose and really didn't need 21" of hose, 12" would be more than adequate. All in all, I'm pleased with the service and will continue to order repair parts.
