    Default Ren32 Troubleshooting--Bad Neutral on the mains

    Hey all. I am looking for ideas on what to do about my Ren32. It is one I have been using to power the under cabinet lights in my kitchen. We recently had the main power company Neutral go bad so the house suffered through schizophrenic voltages for some time before we discovered it. Among the electronics fried by this was the Ren32. The fuse blew which I hoped protected the sensitive electronics but when I replaced the fuse and powered it back up all 5 status LED's come on and stay on. I am wondering/hoping this could just be a bad PIC but with all 5 steady on I am not sure. If I pull J3 they do go off. Appreciate any tips on where to look first.

    Current list of items lost, thanks Duke Energy:

    Definitely reflash the PIC.

    Thanks Wayne. I will give it a try. Unfortunately my pickit3 is 330 miles away right now so it will be a few days.

    That's nice that you let your pickit get out of the house every now and then. Does it at least drop you the occasional post card?

    While you have the PICs out, check and make sure you 4.95-5.0 volts at the test points. After flashing the PICs, swap U4 and U5 ICs if it is still flaky.

    Thanks Wayne. I pulled the PICs to take them home (where the PICKIT is...) and powered it back up. The PWR led lights and I get 4.95+-v on the indicated test point. The status LEDs do not light. I was thinking this was a good sign and left it plugged in for a few minutes so I could write this post. Now I smell burning and it seems the transformer is overheating....too hot to touch after only a few minutes on.

    I'm not an electrician, but the fuse will only help the amperage draw. If your neutral was flaking, you could have had an over voltage issue. We have two phase systems which can give us 220 volts for ovens and dryers. If the neutral floated, the transformer could have be over loaded with voltage. If that's the case the transformer is done.

    The circuitry is the same, so you can use this part of the Troubleshooting guide to find the issue.
