Question about Rinnai RHFE-1004FA 38,400 BTU Energy Saver Ductless Heater - LP Gas
We recently had a Rinnai 1004FA installed. We lost our propane furnace to flooding & now the Rinaai is our main heat source. Because times have been tough, we started out with the "economy" setting, and the propane level on our tanks were 70% when it was installed.
9 days later, our propane tanks were at 30 %!!!!!!!!!!!!
I immediatly called the propane CO, who sent out a repairman to check for a leak.
He promptly told us that when you set it to "economy", it NEVER shuts off!
So much for "energy saving"!
Anyway, he removed the side panel & raised the thermistor to just above the top of the unit.
We thought PROBLEM SOLVED
Umm, not quite!
For the past 3 days, I have it set to 60
Even after reaching the 60 degrees, it will NOT shut off.
It runs CONSTANTLY!!
If I set it to the "low" setting, (55-58 degrees), it will shut off, obviously because the room was just at 60, but min later, on it goes again!
No matter what temp I set it at, it doesn't shut off when it reaches the set temp.
I am totally stressing myself out as to what my next propane bill will be.
I CANNOT afford another $300 bill every 2 weeks :(
Test the thermistor by using an ice cube. Place the cube on the thermistor and see if the unit starts. Then using a warm towel, wrap the thermistor ans see if it stops. Watch the display to see if it is registering the changes in temp. I suspect a bad thermistor.
