How can I check my mail in refund check if the where is my refund  System is not working 


What makes you think the IRS "Where's My Refund" tool is down?  I don't get any indication that it is not operational.   What happens when you try it?
https://www.irs.gov/Refunds
NOTE: When using that tool, use only the Federal refund amount, and not any total refund amount that includes a state refund. The amount to use is on your Federal Form 1040, Line 20a.

 

About how long has it been since you filed?  Did you efile, or did you print, sign, and mail the return?


If you efiled, double-check with this tool to be sure the return was efiled successfully and accepted:

If you printed and mailed the return to the IRS, it takes about 4 weeks to show up in that "Where's My Refund" tool.
