Behmor 1600 Plus - Coffee Roaster

[Makka65]

The saga continues....
The fans are an intermittent problem so Andy diagnosed a faulty PCB. I'll update once it is installed.
Some good news is that when I installed the new front panel, cleaned the sensor area and fixed the afterburner (all at once so it wasn't a controlled experiment) I roasted 100g of beans to 2nd crack in about 10 minutes, not to 1st crack in 16.

Mine died and I couldn’t find one the same size, from memory I got the next size up and re drilled the mounting holes. I rotated it 45 degrees which matched the vent holes better. Resoldered the wires to the plug so it’s still plug and play.

I'm not sure what was going on before but the internal fan is now working fine and I've fixed the after burner. However the side fan is stuffed so off to Jaycar in the morning to see if I can get a replacement.

There's also a video on Youtube of a bloke replacing his PCB. Haven't watched it through.

Thanks artman, I'm thinking ordering a new board and installing it is about my skill level as long as it's plug and play is no soldering....

When I replaced mine a few years back, Behmor support sent me a link to step-by-step instructions with photos. Not sure if they still do this.

Might be worth your while contacting them. Behmor Tech Support – Behmor

Replacing the control board is finicky, but requires no special skills or soldering. Some of the clips can be little mongrels to disconnect, but as long as you are patient you'll be fine.

Check connections of the fans to the control board.

If you are tinkerer/tech capable, unplug fans and feed them 12v DC to see if they are working, if they are then you know its the roaster side.

You can check for power from the control board to the fan connections but be careful as its 240v in there and also you can easily short something with meter probes and fry something further including yourself.

If the fans work with external power and connections are sound, my guess would be its the control board, its quite cheap so might be worth a try?

Bugger, neither of mine are running. Any tips on how to fix this issue please?

[artman]

The small pc fan on the side panel and the other one towards the rear should run whenever the roaster is operational.

Cheers

[Makka65]

Is the fan on the right hand panel supposed to run all the time or only when it needs to cool things down?

[artman]

I have had success cleaning stubborn stains with a scourer (not too harsh variety). The added texture does wonders.

Its broken near the end so in theory should be reparable.........................

When you do the repair, try adding the extra washer on each terminal so the element wire is sandwiched between the 2 washers. Less likely to put a nick in the wire which apparently is where most break.

Someone mentioned that to test the afterburner you just need to hit the cool button and wait about 20 seconds to see if it glows rather than do the 1/4 START dry burn. Much quicker!

[Makka65]

Its broken near the end so in theory should be reparable and its little nook if full of crap! The whole thing is going to benefit from a clean inside and out when I install the new panel.

Oh dear no glow, I'll try your suggestion to repair it but is it only for smoke suppression or will this also be affecting the roast time?

It shouldn't lengthen roasting times, but in the process of trying to repair it you may well clean out a lot of crap that has built up inside the roaster. Note...the last time I fixed my afterburner, simply un-attaching and re-attaching the connectors did the trick (obviously there had been some movement over time....probably from being carried to the roasting bench).
