| Issue / Symptom | Possible Cause & Troubleshooting Steps | | :--- | :--- | | | 1. Replace the fuse. 2. If fuse continues to blow, test both 2.7 mH, 4-pi wound RF chokes (located on the same PCB as high-voltage capacitors). A short circuit in one will prevent operation. 3. Test the transformer. | | No output from transformer | 1. Check the 1 Ohm, 5-watt resistor on the board; it may be blown. 2. Perform resistance checks on the transformer windings. 3. Test transformer secondary voltage. You should measure 700V AC from one end to the center tap and 320-350V AC from the other end to the center tap. Check both secondaries. | | No RF output (tube glows red) | If the unit is a tube-based (FFPF) model and the tube glows bright red when the footswitch is activated, but there is no RF output, suspect a fault in the output stage or tank circuit. | | Unit powers on but no output | 1. Inspect the connectors for the return electrode. Ensure a standard patient plate cannot be mistakenly attached, which could lead to problems. 2. Verify the footswitch and/or handswitch are functioning correctly. |
