testifire 2000 system fault - clearing fan
This happens when a small piece of dirt (about 0.4mm) finds it way into the fan and stops it from turning.
Let’s get that out of there.
Turn off Testifire and remove battery.
Hold Testifire by its handle and tap it firmly against your other hand.
Turn Testifire round and repeat tapping.
Insert battery and run a test to see if the fault has been cleared. You may need to do this several times.
