Frequently Asked Questions

No. It fits specific GMAX and TexSpray models listed above. Always verify against your model/series and manual before ordering.

They are different control box assemblies used on overlapping families of machines. Order by the exact part number specified in your sprayer’s parts list; do not substitute unless Graco lists it as compatible for your model.

Some models require PCB configuration (often via resistor “cut-outs”) to match your sprayer. Follow the exact steps in the Graco service manual for your model.

Skilled users can replace it by following the manual; however, if you are not comfortable with electrical service work, consult an authorized Graco service center.
