What to do if Veco Compressor attempts to start, then stops soon after?
- P
  Paula BrownAug 14, 2025
  If your Veco Compressor starts and then stops, consider these potential causes: * **Power Supply**: The most likely cause is a faulty or inadequate power supply. Monitor the supply voltage at the controller's power terminals before, during, and after start attempts. It should not drop below threshold levels. Check the power supply, ground connections, wiring size and charge the batteries if necessary. * **Relay or Unauthorized Component**: A faulty fan or pump relay, or an unauthorized component, could be the issue. Remove the connectors from the F and + terminals on the controller and try restarting. Note the maximum current draw on these terminals is limited to 0.7 amps at 12v. * **Refrigerant Couplings**: Check that all refrigerant couplings are properly made.

How to prevent excessive frost build-up in my Veco Compressor system?
- S
  Sally AguilarSep 2, 2025
  To prevent excessive frost build-up in your Veco Compressor system, ensure that: * All drains and holes in the box are sealed. * If using a circulating fan, it's not too powerful and doesn't force cold air out of the box. * Door/lid seals are in good condition. Replace if necessary. A good seal should grip a dollar bill when closed. Apply masking tape to suspect areas after defrosting and check for frost build-up after several days to identify leaks.
