I have a Maxspect 420r 320W Razor and a Maxspect 420r 160W. I started having an
issue today with the with the 320W system.

Here is what I am observing. I will describe it from powered off.

1. I turn on Lights
2. All Lights come on and are operating normally
3. After about 10 mins of operating the light shut down
4. best as I can describe, the lights go dark flash once and it looked like the system restarts
5. it repeats the lights Flash once and cycle steps 2 more times
6. then the lights come back on for a few mins and the whole process starts back over

So I have a hypothesis. I think it is a problem with overheating??

I observed and compared the 320W system to how the 160W system is working.
During the whole time I was watching the 320W system, the 4 fans that are in that unit, never came on at all. While the 160W unit fans were running.

Is there some way of trying to do a test and force the Fans to come on?
Might have something to do with a temperature sensor, so the fans themselves work fine, just never kick on. Is there a test this theory if it makes any sense at all? I was thinking because this unit has a passive colling system and fans turn on an off when necessary, could be temperature sensor just never kicked on the fans??

Greatly appreciate your advice on how to get me back up and running and what I should do.

Some additional information. When I was observing, the light power levels were 100%. Around 5 PM I turn the lights back on and in the automatic program levels. Lights have been working fine without issue in the lower light level ranges. Seems to point to temperature as the lower power of the lights does not generate as much heat. I am expecting as the power levels rise toward noon today and the heat rises, the problem will happen again since the fans are not turning on.

Do you have the Razor enclosed in a canopy?

To do a fan test on the Razor:

1. Turn the switch on the power supply to the off position.
2. Press and hold the control knob while turning the switch on the power supply to the on position.
3. The LED screen will say “Fan Test” and turn the fans on.

This will put the Razor into fan test mode and the LCD screen with indicated this mode. Please keep my updated on your progress. The fans on the Razor are thermally controlled to only come on when the fixture body reaches 125F.

Yes it is enclosed in a canopy with ventilation on the back

I performed the test.

What I observed was the low frequency lights came on for a few seconds and then it "cycled" MAXSPECT came up on the LED and it powered back into normal mode. did not seem like it ran the test like it was supposed to.

maybe there is a short in one of the fans?

I put some large PC fans on top the unit and it works fine without any issues, so it never tries to kick on the internal fans which is what appears to cause the problems based on the test you asked me to run..

The replacement fans worked, but unfortunately the unit has stopped working now. The digital display no longer lights up and it acts like it does not have power. I am guessing a board went bad?

The power supply unit green light is light is on.

Not sure how to test it or troubleshoot what is wrong. . everything looks ok.

Your help is greatly appreciated.

Can you send in your light for service?

I could, but I think it is most likely the controller board. When I had the issue with the fans above, when I opened it up, what I found was the fan wires on the controller board were not tucked into the sides and were resting on top of the first light. The wires melted and they ended on touching each other. It was what was causing the short and strange behavior when the fans tried to turn on.

I have a feeling the controller board after being shorted just eventually gave out. Might be easier to just buy a new controller board and give it a try?

I realize it could be a problem with the other 2 driver boards, but based on the root cause of the original problem seems like the issue would be with the controller board.

Thoughts?
