No output, but heats up


The FQ-100 heats up and goes to Ready to Fog, but will not output

Description/Explanation of Issue

This could be due to a faulty pump or clogged heater


  1. Remove all housing screws and eyebolt.
  2. Disconnect the outlet hose from the pump (see picture below)
  3. Plug in the FQ-100 and wait for the Ready to Fog indication
  4. Point the outlet elbow of the pump into a cup and run output at 100%
  5. If there is little to no output then the pump needs to be replaced
  6. If the pump outputs a lot of fluid then the pump is good. The heater is clogged and needs to be replaced.
