Question about Carrier XHB123D X/Y Series Heat/Cool Air Conditioner

1 Answer

Old Gravity Heater kicks off too soon

I'm a novice, but I checked the system over - nothing is wrong with it except its age. Its almost 60 years old. I opened up the fan control box. when I twist the dial counter clockwise the unit would light up. The off is set at 100, the on at 150 and the limit at 200.
Is the unit getting hotter than it should? or is m fan controller not working properly
Thanks

Those are pretty good settings. I might set the fan off to about 85 to get a bit more heat from it. Otherwise you're good. Please give me a fixya rating.

Soot is a sign of incomplete combustion. Cleaning may or may not fix the root cause of this, and given the age/efficiency of the unit, I recommend replacement. If you do have it cleaned, be sure to have the combustion checked.
As to whether this is a DIY project is dependent upon your personal skills, but the fact that you asked is (sorry) a strong indication you should not attempt this job yourself. Hope this helps.

Moved into a house with an existing Rinnai system. We have controllers in the kitchen and bathrooms. My understanding was that you can change the temp by hitting the priority button then up or down as long...


You need a product manual for your tankless computer that heats water.
Look on side of unit for label.
Then google that brand and model and add .pdf to search parameter to find possible resources.
Or try Rinnai website for a dose of promotion about how great their product is.
If unit is a few years old (age of unit accessed with serial number), there might be no manuals posted online since manufacturers often drop manuals from website after a few years, assuming most their products no longer function correctly and thus avoid available knowledge for customer to talk specifics... instead telling customer to call service tech who of course does not have manual either because he is a tech and needs one, but got hired last week to his new esteemed position and gets paid by service call not by successful repair except bonuses for recommending replacement unit.

Read the manual. Especially required maintenance, such as deliming yearly and cleaning water filter.
Note resources for maintaining tankless appear on following link except for different brand tankless computer:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html#de-lime

Also scroll down page to read explanation of high temperature limit for tankless before causing irreversible problem with your computer requiring skilled technician.
Also scroll up on page to read about no error code, since cooler than normal temperatures from tankless computer can be result of common plumbing problems like defective single-handle faucet cartridge. Or power surge, since tankless are not protected from ordinary surge event like power restored after outage.

If your tankless computer is older than 5 years, then assume it will not work better than your 5-year old cell phone or 5-year old laptop, or behave better than 5 year old child. So don't assume you are doing something wrong... just assume it doesn't work despite glossy advertising brochures from tankless manufacturers claiming 20 year lifespan for tankless computers.

Install tank type heater yourself, same day and avoid computer water heaters: Ordinary plumber can fix these units easy.

I have a Servi-star 40 Gal. electric SN# SS 0496B15258, How old is this unit? Thanks, Jim


http://www.buyerschoiceinspections.com/water-heater-ages
There seem to be 2 possible answers: Servi-star vs Servistar

Answer #1: Servi-star by American
1st 2 digits are year, 2nd 2 digits are week

This means water heater was made year 2004, 96th week ....it seems wrong.

Answer #2: Servistar by Craftmaster
1st 2 digits are month, 2nd 2 digits are year

This would mean your water heater was made 4th month of 1996

Which answer is true? 6 years old or 14 years old
If tank had 12 year warranty and came with 2 anode rods, and you have good water, and no stray current on pipes, then tank can last 14 years.
If tank had 6 year warranty and came with one anode rod, and you have hard water and a water softener, and you never changed anode rod or drained tank, then 6 years is a long life for the tank.
