Question about Kenmore TRIO® 77553 Stainless Steel Bottom Freezer French Door Refrigerator

1 Answer

H2S (Rotten Egg Smell in Cold Water and Ice)

We have new kenmore refrigerator model #795.7755. It was installed in early April, 2008. Within the last couple of weeks we are getting a rotten egg smell and bad taste in the water and ice from the dispenser. We are on a public water supply from wells. It is plumbed to the cold side of the house water system, of course. All of the rest of the cold water in the house does not have the problem. If we draw cold water from the tap and cool it overnight it does not have the problem.

The Sears tech was just here and does not have a solution. Sears technical support says it is the fault of the water and we must put in a treatment system. I am about to take the thing back to the store.

I believe there is something in the filter or refrigerator water system that is causing a chemical reaction with the sulfur in the water, much like an aluminum or magnesium anode rod in an electric water heater. Sears says that is not the problem and has washed their hands of the problem. The tech was unable to tell me if the ice cube water goes through the filter first, so we cannot narrow it down that way. He disconnected the feed line to the refrigerator and the water he drew was fine. There is apparently no way to bypass the filter either.

    Since the last post I have learned the following:
    1. My local dealer contacted several of his sources who all say there is nothing in the filter to cause a reaction. They suggest that there may have been some contamination come through the water system that was trapped in the filter and then caused the reaction. They suggest removing the filter, flushing the system and installing a new filter. It is the best advice and service I have received to date.
    2. I learned it is possible to flush the system (both water and ice) with the filter removed without any leaks. I have done so and it appears the H2S is gone, but will know for sure tomorrow.
    3. Since it is possible to obtain water and ice without the filter cartridge installed one can apparently leave it out if one does not need the filtration. With filters costing over $40 and needing to be replaced 2-4 times a year that is probably what we will do, since our public water system is constantly tested. Will let you all know if it presents any problems.

    I have the Kenmore TRIO and have the same problem with the water dispenser. I first noticed an iron taste in the water and when I started trying to run a large volume of water through, I noticed a hydrogen sulfide smell. How do you flush the system with the filter removed?

If you have a braided plastic or braided metal supply line that is your problem. Use a plastic supply line with compression fittings.

How do I know if an egg is rotten?

If you put an egg in a bowl of cold water and it floats discard it. If the egg goes to bottom and lays on its side it is very fresh. If it sinks to the bottom and the other end is up it is about a couple weeks old and still good.

2008 Kia Rio poor acceleration and rotten egg smell. Changed air filter and spark plugs with Busch platinum plugs.

rotten egg smell is attributed to unburned fuel reaching the catalytic converter. There may be an exhaust leak or intake manifold leak that is telling computer to add more fuel then car is capable of burning in cylinders or you could have a to cold of spark plugs hope this helps you solve your problem

We have a rinnai convector gas heater and when we turn it on it fills the room with a horrible gassy smell.

There are a couple of things that can cause this odor. But, being sure it's really a gassy odor is more important. It must smell like "rotten eggs" to be gas. If that is the odor you're smell, turn the heater of and contact an authorized Rinnai dealer for service.

If however the odor does not meet the "rotten egg smell", there are other things that cause the odor, but it's not really from the heater.

If you have painted or stained within the last 2 weeks, the heater has picked up the odor of the fumes (which you probably didn't notice) and has made time 50 times worse. The same holds true for carpet cleaning or new carpeting odors. If this fits the scenario, discontinue using the heater for a week or two until the odors subside. In the meantime, if weather allows, air the house out. Also, remove and clean the heaters filter, before restarting the heater,

I hope this helped you to troubleshoot & solve the problem.

Daylight savings time adjustment

Go to:

The solution appears to be common for all recent Emerson SmartSet(tm) radios (BTW it's not the clock fault, it's the law).

Remarkably Emerson foresaw this, so here we go.

Short version (may require three hands :-) )

DST start:
Press and hold MONTH/DATE and ALARM 1 buttons for at least 3 seconds until the display changes to something like "4 F" (Fourth month, First week) alternating with something like "4. 1" (April 1st, for 2007) or "4. 6" (April 6th, for 2008). While holding down the MONTH/DATE and ALARM 1 buttons, now press the DOWN or "-" Set button (3 times) until "3F2" shows (Third month, second week) alternating with something like "3.11) (March 11th, for 2007) or "3. 9" (March 9th, for 2008). Let go of all buttons and we are now half done.

DST end:
Press and hold MONTH/DATE and ALARM 2 buttons for at least 3 seconds until the display changes to something like "10 L" (Tenth month, Last week) alternating with something like "10.28" (October 28th, for 2007) or "10.26" (October 26th, for 2008). While holding down the MONTH/DATE and ALARM 2 buttons, now press the UP or "+" Set button (1 time) until "11 F" shows (Eleventh month, first week) alternating with something like "11. 4" (November 4th, for 2007) or "11. 2" (November 2nd, for 2008). Let go of all buttons and we are now done.

This should remain until either the lithium battery fails or Congress undoes its work.

BTW the Emerson addendum has a history error. The time change in the first Sunday in April and the last Sunday in October did not start in 1966, but in 1987. Before that starting in 1966 the standard was set at the last Sunday in April and the last Sunday in October. Except for 1974, when it was January 6th, 1974 (DST start) and October 27th, 1974 (DST end) and in 1975 when it was February 23rd, 1975 (DST start) and October 26th, 1975 (DST end). Before 1966, state and local governments had many different rules. Source:
