How to troubleshoot tank heating failure in ASTRO Melting Machines?
- B
  Bryan CarterAug 19, 2025
  If the tank fails to heat on your ASTRO Melting Machine, here are a few things you can check: * First, ensure the system power switch is in the On position. If the switch light doesn't illuminate, the switch might need to be replaced. * Inspect the power-in connections for a proper fit and check for any faulty wires. Also, inspect the connection of the power wires at the main power supply source. * Determine the exact voltage of the melt unit, as insufficient voltage can cause heating problems. Use a voltmeter to check the voltage supplied to the unit. * Refer to the electrical schematic to verify that the melt unit is wired correctly. * Adjust the tank temperature controller. * The overtemperature (O.T.) switch is a safety feature that prevents the melt tank from overheating.

  Matthew WongAug 21, 2025
  If the pump motor on your ASTRO Melting Machine is overloaded, consider the following: 1. Adjust the tank temperature controller. 2. Ensure the pump motor On/Off switch is in the On position. 3. Correctly adjust the flow control valve (F.C.V.) to achieve the desired pumping performance. 4. Check the pump motor as a last step in troubleshooting. 5. Remove any foreign material from the pump and tank. 6. Increase the melt tank and supply hose temperatures. 7. Keep in mind that adhesive formulations can contribute to these issues.
