furnace causing poor tv reception?

Here's one for you guys! Whenever the furnace comes on the cable television picture goes totally pixelated to the point where you can't make out what's on tv, and the audio is "in-audible". As soon as the furnace goes off, it totally clears up within a few seconds. Any ideas, PLEASE??!! Thanks.

Electrical noise from the fan is the most likely source. check out this thread for solutions. //heartlandowners.org/showthread.ph...rence-when-DC-fan-are-running?highlight=noise

Looking at the other thread posted by Silverado23, and considering that the furnace blower is pretty close to the UDC, I'd take a look at the coax you're using to connect to the park's cable feed, and look at the coax connectors to see if there's a problem.

RG-6 Coax cable would certainly be better shielded and help reduce noise than using cheaper RG-59 cable. The cable should have lettering on the cable to indicate the type of cable it is. If you have your excess coax cable coiled up in the UDC it could be contributing to the issue, too.

Okay, for sure this is something my husband will have to try to wrap his head around, my head don't wrap that way. All your replies are appreciated! One more bit of info that might help narrow it down - it's only the living room tv that gives us this trouble, not the one in the upstairs bedroom. Does that give you guys more info as to the MOST likely cause? Thanks again.

A bad connector could be a source of interference. Some TVs are more likely to have interference issues. Weak signals with noise can have a more impact as the signal gets weaker. Depending on how your rig is wired could be why one TV is more likely to have interference than the other.
Easiest to check order.
1. Coils of coax cable that are being used anywhere. Uncoil an spread out a little bit. Just so they are not coiled up.
2. Excessive length of coax cable. Use shorter wire when possible.
3. Cable type should be RG-6 for the hookup wire.
4. Bad/ loose Coax Connectors. Connectors should be tightly connected. and should not be loose or poorly installed on the cable.
5. Try using one or more Ferrite filters that clamp over the wire on the AC power cord on the back of TV and/or on the furnace power/motor wires.
