Have you tried a Google search by the part number?

Customer: replied 1 month ago.
Your search - c21603004A - did not match any documents.
O-rings are a very common part.
O-ring part numbers (from parts diagram):
4 of C21603004A
1 of C21610034A
2 of C21610032A
1 of C21610013A
1 of C21610003A
I suspect the last 4 digits are the 'o-ring size code'. Does this look familiar to you?
Expert:  Airheatman replied 1 month ago.

Not really.I am going to open to other experts who may have more knowledge about this particular unit.

I have opted out of the question to see if perhaps other experts may have more information and can assist.Please do not rate or reply as that will send question back to my desk and delay getting assistance..Please stand by to see if another expert can assist further.Leaving a poor service rating will not automatically refund your money. You have to request a refund if not satisfied with the information provided being accurate.

If no expert can help and you are unsatisfied, we can request a refund of your deposit
