Hi, I am Tech Michael and will be assisting you today. I am a Master Technician that's dedicated to giving you the best Answer possible.
If you are new to the site, this is briefly how it works:
1. We may need some back and forth to exchange information (if needed) and there is no extra cost for replying.
2. I will give you the best possible Answer for your problem without the ability of actually being present with you.
The better you describe the problem, the quicker I can help ;-)
3. Remember to leave a Positive Rating after we're finished. it doesn't cost anything additional to rate kindly;-)
I am only compensated for my time and expertise if you rate kindly.
May I have the make? And the Age ?
Also what fan is this for, please explain, I see only a Granger part # ***** that model #.
Thank you for that.
Is the blower running the way it always was or did something happen?
There are options for this. I will go over with you.
If you are in the US, I can call you to explain and help you do this.
It is possible you will need a part for this depending on your controller and configuration of the motor, depending on if they added a resistor to slow it down etc.
I will send you an offer, if you are in the US please accept that offer and I will call you promptly. If that isn't an option, thats fine with me too, we can work it out this way but it will take a bit longer depending on how long it takes to get me the info I need to help you on this.
Thanks for your patience and understanding as this is a technical issue ;-)
The one you have is actually a 3 speed motor
If all you want o do is slow it down I will explain what to do, its pretty simple if you are handy.
Most of the time when these are setup initially they will be wired as high speed.
But you can check to see, and for sure lower the speed. It depends on whish wire they are using at the moment, it is a something where you will need to check at the relay or circuit board.
I can help you get this done.
