Re: load beeping

I'm not sure what water cooling system you speak of. This is a propane water heater. Possible issues: pressure regulator making noise. Could be dirty or defective. Air in a water line. Excessive scale caused by hard water.

The fan has three speeds. The highest speed is very loud! More than twice as loud as the middle speed. Is this normal? Unit is a KWCU360JSS-1

Yes, it is normal. Actually the energy into a fan is related to the third power or cube of the speed. The turbulence of the air contributes to the noise as well as vibration, etc.

Damper need for Broan Range Hood

I called tech support at Broan and was told they recommend two dampers in cold climates at in the wall cap and one on the unit. They make the damper,
(#BP87-7"), that attaches to the round duct plate that comes with the hood. Strangely the unit does not include a round damper and the seller LOWES did not have it, also checked Home Depot,.
The Tech said they can't get stores to stock it. I checked at a local supplier of all kinds of plumbing, heating, and cooling supplies and they only had basic 7" dampers which, I was told would probably be too heavy, and be manual. I ordered it through Amazon/True Value ($11.56 w/ shipping, shipping more than cost of damper). Tech indicated that the 2nd (unit damper) is optional and may not be needed if in a warm climate. I would suggest that Broan include the $5.00 item in their unit or at least sellers stock it.

Beeping sound coming from fan

Open wiring area up and find where noise is coming from. There is a electronics board in some fans that might have a warning buzzer of some kind.

Is this the one with the slide power unit? If so, the slider could be defective. First, have a look at the it full of gunk? If so, you might be able to clean it out. With the power off, get some brake cleaner from the local auto supply guy. Spray it liberally into the slider and move it around...The dripage will be messy. Put a bunch of paper toweling under it to catch the stuff. It is not flammable but you should wait for it to dry for a few minutes before restoring power. Still with the power off and the motor/fan exposed...does it turn easily? If not, you may have an issue there. Gunk or bad bearings. Fix that up.

these heaters work when a pressure drop is sensed in the water supply line. The pressure sensor is likely blocked with sediment from the city supply. You may want to call for service.

The magnetron may not be cooling properly and the overheat is what is causing the shut down. The internal cooling fan will need to be checked for proper operation.
