I have a rinnai direct vent wall furnace about 4 years old. The thermostat is erratic. How do I fix it? Have others had this problem?.

same problem, im sure it is due to the sensor that reads the return air temp. my wire has moved, getting erratic readings too. long yellow wire in the unit, not sure where it should be mounted though

When I replaced my unit, which was cracked, all I did was remove & replace- my furnace has an external sensor. I think you would be fine doing the same thing.

Depending on the age of your stove the problem you are facing seem, most likely, to be the sensor control. Have a qualified technician check it out before investing tons of money trying to solve the problem yourself.

The answer lies in another question. Is your furnace turning on and off a the appropriate times? If it is then the thermostat is doing what it is designed to do, control room temperature. The one you have chosen is very sensitive, plus or minus one degree. It is possible that the thermostat does not see any major changes in temperatures, since the wall the thermostat is mounted on, is a thermal mass that can buffer the actual air temperature variations in the room. Try placing a good thermometer next to the thermostat and see if there is a difference in what they are reading.

More information is neededsuch as what system do you have. Is it just a furnace or does it incorporate central air. And what connections were on the old thermostat (w,r,y,g)?

I wish I could answer this. I have not had much luck with my duct control either.Would not recommend.Iam guessing there is airflow from furnace unit causing it to stay on . im looking for another solution

If this happens turn the thermostat clockwise to a hotter setting . Up to and as far as completely, turned to the full stop position . If this does not bring the hot air back on . You have a defective unit.The only way the thermostat should work.Is that if the room reaches the maximum temperature . That the thermostat [dial ] is set to respond to. It should turn off both fan and heat. then when it drops below that setting again. It turns on both fan and heat together. If that is not what yours is doing. It needs to be replaced or repaired .If thats possible.But that would only be,,, to my knowledge,, under any [ short ] warranty it comes with If this happens turn the thermostat clockwise to a hotter setting .

I had the same problem. I first replaced the over protection switch and the hi limit switch. heater then came on and as you have it just ran hot even in air dry, so I replaced the thermostat and the heater still remain hot and brightly glowing. I talked to a repairman and he said to check the heater for a short to ground. It was shorted. Replaced the element that only had one of the ceramic element holders broke. This fixed my problem. I hope this helps.

Most likely the heat element burned out. Local repair shops would not fix it even tho still on warranty. Returned the unit to Oreck. They sent a new one which works ok.

Hello, the exact same happened to mine after about 1 year of use. I removed the unit, drained it and opened up the top. On mine, one of the connections from the thermostat to the heating element had broken. I repaired mine with some silver solder and a small butane torch. It's been working great ever since. That was approx 2 years ago. My advice is, it's not working anyway, so just tinker around with it. Just remember to put the heating element in water before you power it up or you may burn it up.

Mine smelled funny the first time or two. Be sure to move it out from any walls so it has plenty of vent room. I've had mine since Xmas and it doesn't smell anymore. I think it might have something to do with the fans because it only smelled when I used the convection oven.

The regulator is probably bad. I had this same problem on this model. Had to replace the grill. Not sure why it does, but something happens and it does not let enough gas through to heat, or, no gas flow at all. I tried turning the adjuster knob slowly from low to hi and back, several times. No go.

It would appear you may have a defective thermostat. Only replacement of thermostat would cure the problem. Entire unit may have to be replaced, as a replacement thermostat may not be available.

I'm currently having the same issue. I bought a hand held gas detector & discovered that my new stove has a slight leak from one of the rings! I am waiting on a part from the stove manufacturer to be available (by next week) and will see if it changes the situation! I will recalibrate as directed by the supplier of the hood and will follow up here when I feel either all is okay or status quo!

I would love to help - but mine was put in by a contractor (on several tries) who said the fan/vent/heater was a b---- to put in, even with the special wall switch. I hope you get it figured out, because the fan/vent/heater is wonderful and I am glad I purchased it.

Other than having another faulty thermostat, I would check the mounting. If not mounted correctly the unit may not operate as designed. One other thing, be sure you are exceeding the room temperature when operating the unit. If the room temperature is higher than the thermostat setting it will not fire.

I too haven't had any issues. There are heat settings that you can adjust. If it doesn't heat up, you may have a defective unit.
