Hi,
I am looking for either a manual or a circuit diagram for a C-Mark MR2450 amplifier. I have one fan that runs slowly all the time and one that doesnt. are they https://www.amazon.com/Jhua-adjustment-Rotatable-Ventilation-Circulator/dp/B01DUCAY0K - dual speed fans or on all the time ? Are they on thermostats ? Is there a replacement fan available to retrofit ? Any information greatly appreciated. Regards Dan.

Fans should permanently be on. If you have a lazy fan then swap fans from left to right and see if it carry's on. If it does then the fan is broke. Highly doubt it will be the circuit that drives the fans.

Hi. I swapped the left hand fan over and it worked on the right side.
Therefore I have two good fans and a problem on the left control. Are the temp sensors n/o or n/c ? A drawing would be ace. Thanks Dan |

Do the fans go through a relay switch ?
