Hot Water Heater Problems this week
Our water heater is a Suburban SW D 6. It operates on propane only.
I turned on the water heater and after a period of time (unsure how much) I noticed a cloud of steam coming from the side of the trailer. It was coming from the water pouring out the pressure relief valve. I turned off the toggle switch for the water heater and the water stopped coming from the relief valve.
A few hours later I pressed the reset button and turned on the water heater again. A period of time passed (unsure exactly as I wasn't timing events. I am guessing about a half hour) and I noticed I could still hear the propane flame. I turned off the water heater and measured again. The water was about 75 degrees C (about 170 F).
I tried later and the heater would not come on while measured water temp was about 120 degrees.
The next morning the water heater worked fine when I turned on the toggle switch. However, to be on the safe side, I turned if off after 15 minutes of heating.
I know the heater has thermostats that will open pressure relief valve if the temp exceeds 180 F and will not start heater if water temp is above 110 F.
So, I am guessing that the thermostat that is supposed to turn off the propane flame when the water reaches the appropriate temp is not working. I am basing this on the water steaming out the pressure relief valve and later the propane flame still burning while the water temp was at least 170. However, I am guessing it must be a different thermostat that prevents the flame from starting if the water temp inside the heater is above 110.
Is this an easy fix or should I make a dealer appointment? Until the problem is resolved I am noting the time when I turn on the water heater and am making sure to turn in off after 15 - 20 min of heating. That got us through the rest of our trip without a cloud of steam coming from our trailer.
