Dimmer - APD

[ILoveControl]

So been away for about three weeks come back home to find my garage light Adaptive Phase Dimmer flashing RED LED on the top LED. Try to reset it 9-9-9 nothing. Go to composer open it up in composer see:

Mosfet Failure

 

The "Phase" is set to auto detect and picks up:

Reverse Phase

 

Composer can still "Communicate" with it, but resetting the error does nothing to it. Not sure what the error message means or is. Any ideas?

 

I can see the network connectivity (full strength) and Composer can still communicate with it but no light control.

Hmmm a hard reset on the circuit breaker for that area at the power board seems to have sorted it out. Still .... is there no way to soft reset the switch without dropping the power to that whole area and what does Modfet Failure mean?

same issue faced

i did 15-0-0 to reset/reboot

A Mosfet is the transistor-like device that controls the load.

 

Typically, if a device is reporting mosfet failures, it's due to trying to control the wrong type of lights with the dimmer.

 

One of the things that will likely set these off is if you're trying to control a non-dimmable load on a dimmer:

 

This issue has popped up on the Control4 Dealer forums, here's a response from the Lighting Product Manager:

 

-------------------

Non-dimmable loads should NOT be used with APDs or Keypad Dimmers. This is not a supported nor regulatory approved configuration and will, in all likelihood, damage the dimmer or the load at some point.

The APD and KD have built-in minimum ramp rates that can't be overridden. Even if you set the ramp rates to zero, the dimmer itself enforces a minimum ramp of about 100ms. That's necessary to protect the electronics and to get the dimmer through regulatory approvals. Using a non-dimmable load with either the APD or KD will very likely trip the MOSFETfault. It may have worked prior to 2.6 but this is exactly the type of use we're trying to prevent. 

-------------------

 

If your dimmer is firing Mosfet faults and it *is* a dimmable load, it's possible the load is not compatible with the specific dimmer, and you may have better luck replacing it with a specific type dimmer (forward phase, for example).

 

Anything other than incandescent lighting can get pretty complicated, unfortunately, and you see similar issues with other dimmers, not just Control4.

 

Sorry you've been having the issue.

I'm getting this same mosfet failure and I'm running out of ideas

 

the lights to be dimmed is

I tried putting it into reverse phase manually.

 

Still giving me the mosfet failure error, and with red light blinking on the dimmer

 

any ideas?

Have the same error. Worked with exactly the same led dimmable globes for the past 8 months without issues. The issue started after the upgrade to 2.6 OS. Could that be the issue?

I see at the dimmer puck's property settings there is an option to "Convert to V2 driver". Could this solve the problem?

I changed to another new apd , and the problem went away

I have seen this on adaptive phase dimmers, as RyanE said trying to dim a bulb that wasn't meant to be dimmed - CFL BR30s if I recall. Swapped out for regular incandescent or dimmable LEDs and the error went away after a reset.
