Thanks for the suggestions. I will try the Seafoam and carb spray, Seafoam (not used this before and not sure what it is) and will check bout the time delay module. Also, not sure what marvel is. I see on internet a product called Marvel mystery oil. Is that it? I didn't let the gas run when I changed filter. My tank is almost empty. Should I just take fuel filter out and let the gas run out of the line and then get new gas? Is the intermittent coughing and sputtering something caused by sticky valves occurr more under load?

Inteference problems are a pain to diagnose, but the good news is that in just about every case the cause can be located. Since your inteference problem is recent you should look for changes that may have occured in and around your home recently. Also, since hte interference affects sets connected to both inside and outside antennas it is safe to rule out cable and ground issues, atleast as far as the antennas go. Since the inteference also affects all channels, it is rather unlikely that weather conditions alone are to blame. Weather conditions typically will either 1.) attenuate distance signals making them noisier or blanking them out completely, or 2.) allowing distant signals on the same channel to travel farther thus causing inteference to nearby stations. While #2 could still be a likely cause, I'm thinkin something electrical is to blame. The questions I normally as are: 1. Have you purchases/installed/connected any electronics, appliances, computers, ANYTHING electric around the time the inteference began? 2. To the best of your knowledge has any of your immediate neighbors done the same in regards to new electrical equipment. 3. Look for cause-effect relationships. Does the inteference start when someone dries their hair, uses an electric shaver, does laundry, etc. 4. Any new construction nearby? Power tools, especially arc welders can cause electrical noise from longer distances, sometimes ranging from hundreds to thousands of feet. 5. Probably not applicable down there, but electric heat and water heaters if they develop a problem can cause inteference too. There are other tips, but I think you get the idea. If you still get stuck, don't hesitate to call one of your local tv stations and ask for some guidance. Make sure you ask for someone in the engineering department, they are used to dealing with these issues on a regular basis. Best of luck! - Steve

Exciting! Thank goodness to my sous vide setup. I was cooking like mad the past 8 days for a lot of people. I was able to serve prime ribs, ducks, steaks, pork rib roasts, fish, short ribs, pork spare ribs, ---- all perfectly done, perfectly hot, at the perfect serving time --- all with no stress! I can see why restaurants like to use sous vide for their cooking. Your system: The pump should run full time. Only the heater is to be controlled by the controller. The pump you have is good. I use a different pump which has an 110vac motor. Much simpler than your brushless DC motor. A DC brushless motor has electronics inside (Hall Effect Device) which is more heat sensitive. You should get backups for all components, so that for long cooks you will not be stuck. Also get a couple of spare temperature sensors. Don't buy the sensor alone, can be $7.00 to $10.00. But this instead: http://www.ebay.com/itm/New-Digital-LCD-Thermometer-For-Aquarium-Freezer-H155-/200978818608?pt=LH_DefaultDomain_0amp;hash=item2ecb456630 The sensor is the same thing, much cheaper. I had to replace my senor, which did last a few years of non-stop use. Have fun and let us know your progress. dcarch

Thanks, ronnatalie. All connections were checked/rechecked - everything seems fine and the lights are working again. We will continue to watch these switches and if intermittent behavior starts again - will start replacing them. Do you think that the dimmer switch is the most likely culprit? Can this be due to faulty 3-way and 4-way switches we have by the door and on the wall? I was thinking start replacing with those two.
