How To Install Speed Control for Fireplace Blower - Midwest Hearth

[@rickgripman3138]

I installed a new rheostat but only have one speed, I put both wires from the rheostat on both black wires but only can get one speed

Will a rheostat work to increase fan speed on pelletstove that is controlled by a computer board? The pellet stove has to be set at highest heat setting to blow a little, thus burning up wood pellets unnecessarily...thanks for your time and I await a reply before I slap on a rheostat.

A rheostat will only decrease the speed of a fan. The "highest" setting on a rheostat will be equivalent to the speed if you wired the fan direct.

Was there a red wire on your blower? I have the same blower but I have a red wire..

Regardless of wire colors, you want to interrupt the power wire with the speed controller.
