Will your melter not power up?
Is the melter, hose and/or applicator heads not performing to the settings on the circuitry?
You may need a new circuit board. If this is the case, you have an alternative to the OEM.
Why buy new when you can exchange your old board for a less expensive rebuilt Nordson® board?
A warranty is provided and the savings can be as much as 1/2 over the new price.
