Expediting the batch is not always possible due to CM jobs in the queue, cost, long lead times on required components, or other. At times, the next batch is not scheduled soon enough (i.e.: underestimated demand) or is delayed (i.e.: component shortages, revision changes needed) which leads to a shortage. When companies rely on off shore manufacturing, they generally commission large batches of their product to the contract manufacturer (CM) and schedule the next production run for the next batch based on estimated demand. JoefromBoston - Long periods of shortage do not necessarily equate to product issues.

Currently the only way I know of is to add a Dimmer Bypass and they run about $15 each. Leading edge dimmers are more sensitive to LED lights. I say that because I've come to the conclusion that HS dimmers are leading and not trailing edge dimmers. If they do then it's likely that the LEDs you're using draw such little power that the triac is locking up. If you having failure try putting one standard incandescent bulbs in the group and see if things work better. HS dimmers seem to be having problem with some types of LED bulbs. Heck I've had dimmers in service for well over 10 years without a single failure and there is not reason we shouldn't see the same with Z-Wave dimmers. I'm assuming that HS is seriously reviewing fail devices to determine why they failed and hopefully are using an outside lab that has the specialized equipment needed to determine what a device failed.ĭevices like dimmers shouldn't normally fail in the first three to five years of service. The third cause is user abuse such as overloading the devices.Again outside labs can better determine this than trying to do it in house. These may be as simple and operating a device too close or just past its maximum ratings or not providing sufficient heat-sinking of power level components. In these cause HS needs to have outside labs to determine what these devices fail. This could be do too many things that goes into producing devices. The first cause is a problem during the assembly process.I've been reading this and it seems to me that there are three main causes. Rjh - this is in addition to what I have already reported to you. There has to be something wrong with the design for this to happen so reliably on multiple ceiling fans. I will likely have to get the dimmer replaced as well given it likely failed as in the previous several cases.
HAI LEVITON UPB DIMMER FOR LED LIGHTS UPGRADE
I purchased the same retrofit LED module and will upgrade the ceiling fan whilst removing the wattage limiter. Later I tried to turn the lights on again and while the LEDs show it is on, the light is not on. A couple days ago I turned on the lights and I heard a click and the lights went off. In several instances I heard the clicking of a relay so I suspect it has something to do with LED in-rush current and these specific dimmers as my previous Leviton Vizia RF+ dimmers worked fine for over 4 years. The other three rooms with this same ceiling fan all had the same issues. One was retrofitted with a LED module that works perfectly with the WD200 and the wattage limiter was removed (module is within spec, and bulbs are no longer interchangeable) so no issues there. I have 4 rooms with the same small ceiling fan.
