I have a Zinwell WB68 multiswitch mounted in my attic (Florida). When I was up there working on my TV antenna switch, I put my hand on the WB68 and it is very hot. It was so hot, I could barely hold my hand on it.

The attic is about 120 degrees in the summer. I know this is contributing to the heat but is it normal for this switch to run really hot?
Thanks

I had my multiswitch in the attic in RI, and in the summer it is easily 120 degrees there. The switch was never more than warm to the touch.

Start disconnecting cables, one by one, and give 10-15 min to check temp after that.

Disconnecting cables from the house side will allow it cool down. There is no power source at the dish. But the problem is probably that the tech left some of those chrome terminators on unused OUTPUTS. This is shorting the switch, making it heat up.

In the trash, with the box the switch came in, there is a tech memo to not use those terminators on outputs.

Report back what the problem turned out to be.

It is normal for them to be warm, but it shouldn't be so hot you can't hold your hand on it, except in the summer when your attic is 150+ degrees and convection can't keep the switch cooled. It should be swapped out, which should be free if you have the protection plan or if it's been less than 90 days since you were installed.

This would be my first guess.

The new WB68s that come with the weather boots already installed also now come with metal caps. These caps DO NOT have the 75 ohm resister in them and are fine to leave on.

I just check the mutliswitch again. The attic is much cooler now, about 90 degrees. The switch is not hot anymore - it is "very" warm. There are no metal caps on unsed connectors, just plastic covers. I guess I was overly concerned for nothing.

BTW, what are the two Flex-ports used for?

The flex ports are for adding seperate dishes for the 95 sat (internationals) and/or 72.5 dish for SD locals (going away "soon" )

Umm, the international dish and the 72.5 dish for locals if your market does not have locals on 119...
