be careful the anode wire carries the high voltage.

Why was I told the aluminum anode would not work in my Whirlpool WH? Had it removed today after three weeks and it was covered with matter. Now have $60 Whirlpool rod installed on my lifetime warranty...

1) Ask question on pro water heater site run by foremost anode expert, and also ask about the power anode rod that works electrically instead of chemically and will not have repeated problem you describe:

2) More info about anodes:

My Fender Deville has suddenly lost power (this is the 60 watt 2x12 model from around 1998) . It still has some volume, but much less than the last time I played it. It has had a history of some minor...

You will need to isolate the fault to a particular stage.
The two large valves are the power output valves and operate in push/pull mode. The next stage is the phase splitter and driver stage. The next stage is the tone control and compensation. The first stage is the pre amplifier stage. To eliminate the output and drive stage you will need to inject a signal at the top end of the master volume control. Touching this point wth a screw driver will inject enough hum to give a strong buzz from the speaker, if this is the case then fault is in pre amp of tone circuity if not. Check screen feed resistors for open circuit (wire wound resistors to screen pins of output valves). Check resistors to anode and cathode pins of phase splitter for increase in value. If the output stage seems ok then isolate the fault further by touching the screw drive to the grid of the valve in the tone network and then the pre amp valve. The buzz will get louder as you progress if the stage is working ok. If not check anode voltages and resistors.
WARNING. dangerous high voltages exist in the circuits. Only ever use one hand when making contact tests, keep the other one in your pocket. If you feel this help is beyond you then please seek professional help.
All the very best from Vintie

I was having video problem on my crt sony kv-g21p2. audio is fine and 1000volt is not producing but 115 volt is producing and i have replaced new fbt but still the same

good day since you have been already replaced the fly back transformer as you said so meaning the problem is not the FBT. any way here are some of my recommendation to isolate the problem .
  1. unplug the tv unit and then unscrew to open the back cover and gain access the crt chassis.
  2. now with use of flat screw driver remove the anode cap of fly back transformer make sure you discharge first for your are you going to discharge the voltage,get single wire then flat screw driver now strip one end of the wire and tie it to the flat screw driver the other end of the wire splice at the chassis ground of picture tube. and then insert the end portion of the flat screw driver to the anode cap to discharge the voltage left. you can now pull out the anode cap.
  3. by this time you will turn on the tv unit place the anode cap in a safe position not to damage the board be careful its a high voltage. plug the power cord and turn on then observed if their is an arching at the anode cap usually a blue color just to know if the high voltage is present.
  4. if their is a high voltage that means horizontal output transistor is good thats why the fly back transformer is on. your next step is to check the secondary voltage of fly back transformer with the use of digital tester or even an analog tester to know why their is no 1000v. check bad fusible resistor near the fly back transformer usually a 22ohms value this is where the 1000v pass through going to chroma board or video board. if open or no resistance pull out the said part and then replace with the same rating value.check also shorted diode connected to the resistor sometimes it was the cause why the resistor get bad.
  5. after you replaced defective part insert again the anode cap for testing once again be careful.
  6. now turn on again the tv unit then observed if their is a video on the screen check also the heater voltage at the chroma board if present usually about 2Vac something you will also noticed their is a light at the neck of the picture tube.
  7. if the 1000V is present the heater and the B+ supply voltage i'm sure the video will come out. i hope those steps that i give to you will help to fix your problem thanks for choosing the fixya if you have further question i'm glad to help you.

Water has a sulfa oder,when not in use. what is the solution?

Generally tank odors are bacteria reacting with anode rod.
Make sure odor is isolated to water heater, and on hot water line only so you know water heater is best suspect.
Change anode rod.

Your plumber will know all about anode rods and will have tools or impact wrench for removing old anode rod.

Where is anode rod located on 100 Gallon rheem water heater natural gas

Anode rods for tank-type water heaters are located on top of tank.
This is true since anodes are about 44" long.
Top of anode is standard 1-1/16" hex nut.
Anodes can be located in 2 different places: either directly screwed into top of tank -or- attached to hot water nipple.
Most times the exploded parts diagram in manual simply shows 'anode rod' without specifing exact location. If your tank has long warranty, then it can have two anode rods, and 1 will be on top and the other probably attached to hot water nipple, or there could be two anodes screwed into top of tank.

If anode is screwed into top of tank, then it will be under a plastic cap -or- it will be concealed under the top cover of tank.
Look for plastic cap, and if none shows, then remove screws holding down metal cover and look there for 1-1/16" hex nut.
Lastly, remove hot water nipple and check for anode located there.
If you have 2 anode rods, then replace with same metal for each.

Hello, cracklin. Now that everyone has told you what it is, I wil tell you how to fixit, sense we are a fixit site.

I was trying to help you out here. Maybe this will help some? I was going backto some customers that asked questions in the recent past and even fartherback. It appeared that no one answeredsome of them, So, I thought I would take some of my personal time to see if Ican help. Even though this Informational site may not have your exact model orbrand, this site will help you a lot. Here is a site link about everything you want to know about hot waterheaters and possibly yours, from
repair to trouble shooting it.

Please if this helped you at all, if you can find the time and in your heart torate my help and some kind words written would be appreciated for my free help, I would appreciate it.

Here is also my direct link to my own pages of other areas of my expertise forother problems you might have in Automotive, Appliance, and Electronics. DropIn anytime for my help.

Toshiba CF36G50 Noisy when you turn it on

that sound is comming from the tube anode it is leaking you have to discharge the high voltage from the anode cap,then take off the cap clean the area with alcohol and put some red or clear silicone on the cap and anode connection replace back the cap on the tube leave to dry for about half hour,this will remedy your problem,no more static.good luck.
