Re: Anyone repair anything today?

In other news, I replaced our range hood fan. It's so much quieter and I hate our house builders so much more. 1) Above the hood is a cupboard, they made it a very shallow cupboard with no blocking behind it so they could vent vertically and then do a 90 out the wall. This meant that the old one was...

Re: Anyone repair anything today?

You need to turn it off and then watch it when you turn it on.

Does it actually ignite the flame and have the flame touching the flame sensor, but then shutoff and run a purge cycle? That would suggest a bad flame sensor.

If it doesn't actually light the flame then that suggests a bad igniter.

Re: Anyone repair anything today?

Flame sensor needing cleaning is common in gas appliances. Quick rub with wire wool to get the crud off and everything works fine again. If your furnace needed it then probably worth running around and doing things like the gas water heater at the same time.

Just because the signal strength is strong doesn't mean that they aren't dropping packets all over the place. All WiFi drivers are garbage.

Re: Alternatives to renting a fiber DSL gateway?

Good point, I'd been looking at the ActionTec box. It seems that doesn't have any fiber ports (i.e. SFP / SFP+ or similar) so something else has to be converting from the glass to something that will work with that router. It does have a MoCA 2.0 port, but if that is not being used and there is a fi...

Re: Alternatives to renting a fiber DSL gateway?

Fiber (glass) is different from DSL (copper). What is the actual connection that they have? If it is over DSL is it ADSL, ADSL2, VDSL, pair bonded? Only then can we tell what will work with what they have.

Soyuz launch abort at about 2 minutes of flight time, which is when boosters separate. Crew is safe after a ballistic reentry. Sounds like it was a lot gentler than the ballistic reentry in 1975 which pulled 21G :o but still rough at more than 6 G. This is going to be interesting, do you continue t...

Another podium where the Mercedes drivers are both upset and Vettel happy, just like Monaco in 2015.

I thought that they would switch the drivers back around at the end to not take Bottas' win from him, but I can understand the logic in giving Hamilton 7 more points.
