Looking for replacement part for "amerock roto part# 1880270" roof window operator. Anderson Window is requiring far too much, nearly the cost of the entire original roof window. Do you have a source which sells part, equivalent or functioning rebuilt/reconditioned part at much lower than $290? I do not need springs or other brackets.
Andersen stopped making this operator, as far as we know, so the decreasing supply has probably spiked the price, as you can see. We can't obtain it for any cheaper than you can, sadly.
I asked a hardware researcher, who feels your pain, and suggests the only possibility he believes could possibly work as an alternative: the 39-390 Andersen awning operator. It seems to have the correct sliding shoes to mimic the Andersen roof operator you need. See if you can possibly retrofit this to your window and save some money. It's hard to say if it will work, as far as the length of the arms and the position of the screw-holes needed to mount it.
Paint thinner was probably the best choice of solvent. You might need a little more grease afterwards with acetone versus kerosene (to get back to a normal level of lubrication), but you dissolve more of the hardened grease with acetone than you would with kero. All's well that ends well.
For the new lubricant, I would recommend a modest smear of white grease on the gears to start. Then, you can use a silicone spray for the rest of your maintenance; things like lubricating the arms and tracks. Silicone is thinner, dries softer, and collects less dust than petroleum-based oils/WD40/etc., so you can try to avoid the operator gunking up again for as long as possible.
Glad to hear you avoided a costly replacement!
Hello! I have heard that the 39-390 operators work, yes. However in each case I have been told that it takes a certain amount of handiwork to install, due to the differences between the old and new operators. If you are not handy yourself then I would recommend having a local professional do the job for you, as it takes altering the shape of the sill.
Hello,
I've added your request to another thread referencing the same 1880270 Andersen product number. Take a look and see if you might be able to adapt the 39-390 operator mentioned in this post to work for your repair. Thanks for posting.
