Does the Coal-Trol Burn Out Motors?

I have a Reading Junita stove with a Coal-Trol. I have been reading on various forums that using the Coal-Trol will cause the motors to burn out of the stove because of the variable speed. Is this true?

I can hear my convection running at various speeds, does the combustion speed vary too?

If this does burn out motors, are there other types of motors I could switch too? I think the Coal-Trol does a great job.

Thanks
Pat

Coal-trol does not burn out motors. With that being said there where earlier versions of firmware that did not start motors at proper levels but that has been dealt with.

Since you have a Reading stove w/ a TriBurner, you would of already had to add a separate combustion blower in order to be able to use a Coal trol. Most liklely it is a shaded-pole motor...inexpensive to manufacture and expensive to operate, while being the most short lived motor...guess who is the winner and who is the loser with this arrangement.

The wise consumer would look to find suitable replacements in PSC motors types.
Uses half the energy and lasts twice as long as the shaded-pole motors. Ball-bearings seem to be standard on these also.

I spoke with Neil at Coal-Trol and he told me that using the controller will not shorten the life of the combustion blower. The blower runs at constant speed.

Thanks Neil for the information

I think I remember seeing an update about setting a MIN CFM (or %) for the convection blower, since the blower cools itself, it needs to run at a min. speed and not to overheat.

I think I have my convection CFM set to 30 or 40 on my one stove. it's been running fine for 8 years now? never had to replace a motor.

My combustion blower runs 100% full all the time. the Convection blower varies with the Feed Rate and heat requirements.
