Change temperature in Glacier Bay shower faucet # 12783

Hi Ellen

I'm not sure I have the right valve, but the link that sent me to the PDF file below showed the valve as being a bunch of different model numbers (including the number you gave).

Check out the link:

Steps 12-13 show how to adjust the temperature limiting device!

If this isn't your valve the steps should be pretty similar to the above.

Let me know how you make out, OK?

Good luck!

Mark
