LT 155 quits running after about 10 minutes of operation.
Comments (6)I have an LT 155 that was doing the same thing as yours. It would start hard, run about once around the yard, then sputter as if there was a gas problem and die. After much fuss it would restart and I could get the yard mowed. I spent three seasons, one trip to the dealer and one on site visit to get it resolved. I put in new gas filters, spark plugs, etc. but they did not solve the problem.. It was not a gas problem even though after running for a while the filter appear not to have gas. It was not any of the interlocks, though I spent hours checking circuits. It was the condenser. If you have a problem it would be cheaper to buy a new condenser and install it yourself rather than spending the money and time to service or have the tractor serviced hoping to find the problem....See MoreNew cold tap runs hot--plumbing advice?
Comments (3)Is the hot water supply pipe touching the cold water supply pipe somewhere? Maybe the hot water is warming up the cold water where they touch, so you get hot water for a while at first. Something to check....See MoreNew water heater losing heat after 10 minutes
Comments (14)Continuity test on the elements, otherwise wired incorrect as 110 instead of 220. If elements are good and wired correctly (should be a double pole breaker) then possibly bad thermostat either upper or lower. DavidR had good advice. As far as safety concerns. Factory setting is 120, which still doesnt kill everything but they dont set it higher because without mitigation it would burn people. I would recommend a tank booster which allows you to set the temp to 140 on the storage tank, which allows you to really kill anything in the tank, maintain hot water longer during use, and also acts as a mixing valve to prevent scalding. That link has lots of useful info. If the tank booster seems too good to be true, then go with a thermostatic mixing valve on the hot side before distribution to the house instead. Side note: I have mine set to 150 and only achieve about 140, I have plumbed in temperature gauges to the cold, hot premix and hot after mix. Temp readings arent real unless you are running water for a bit, so best to check when doing a load of laundry or someone taking a shower....See MoreNew water heater gets cold after running bath for a minute or two.
Comments (15)If it was a dip tube issue on the old unit, the new water heater would have a new, intact dip tube and should have taken care of that. Is the water heater plumbed backwards? That could cause what you are experiencing. Looking at the front of the heater, the right connection is usually the cold water inlet side and the left is the hot water outlet side, it may also be labelled/stamped into the WH shell. Feel the piping with your hands as hot water is removed from the tank. Try a test: Have someone at the water heater to feel the hot water discharge pipe as water is run at the bath. Does the discharge pipe turn cool in coincidence with the tub water turning cooler? It should only go cooler after 30+ gallons have been used. If it cools sooner, get the plumber back to check things out. Is there a tempering valve near the water heater? Tempering valve sense the hot water temperature and mix in cold water to maintain a constant discharge temp to prevent scalding. Or, some set the water heater at a very high temp and use a tempering valve to give them extra gallonage of hot water. If you had one that was faulty, or set to too cold a temperature, you could experience what you describe. They might look like this: https://www.supplyhouse.com/Mixing-Valves-322000. Also, the tempering valve does not have to be near the water heater, it could be installed closer to or very near the tub/bathroom....See Moresombreuil_mongrel
