Rinnai 2001 Gas Heater - turn off


My gas heater turns off after about ten minutes. I am assuming it is a safety feature when the thermostat gets to hot. The cuase I don't know. I paid a repairer $99.00 12 months ago to vacuum the heater, but it still keeps happening. Any ideas?

Cheers, David

    I have a Rinnai 2001 Gas heater that the pilot light ignites the main flame, then after several minutes when it heats up the fan comes on but the main flame goes out and the fan continues to run until cool, then the fan turns off and you can start the pilot light and continue the cycle. I have disconnected the fan and the main flame will continue to run.
    Any hints would be greatly appreciated.

    I have exactly the same problem except the space heater is Rinnai model REH300FTC. I vacuumed it but to no use. Can you tell me did you fixed your problem? What was wrong? Or shall I rather look for a new heater?

If, like me you have a Rinnai **** heater, with a PCB Assembly, then thats what the problem is. Look at around $500+ installation. These PCB's are not repairable. For $500, I am going to trash this heater and get something from a company that does not want to screw me after I have trusted them to live up to their "REPUTATION". Do not support companies that do not support their customers!

Robertshaw thermostat will not shut off heat

gas or electric furnace? sounds like bad sticking t-stat but could be sequencer or gas valve. The fan will continue to run if the unit is hot safety feature so the fact that the fan continues to run does not mean the t-stat is diffidently bad.

Hi ,I have a rinnai blaze 21TR, The lock is on and we have lost the manual so don't know how to get it off. Not sure how it go on in the first place. I'm assuming that is what the problem is as...

The heater's electronics should reset, if you turn the Master ON/OFF Switch to OFF and unplug the heater for 30 minutes. Then plug it back in, turn the Master ON/OFF Switch to ON. The electronics should revert back to the original factory settings. From there, you can reset them the way you had them - minus the lock out feature.

Hope this helped you solve the problem. Please let me know. Thanks.

Our coleman fireplace insert starts to warm and then shorts out

Not sure if you have an electric fireplace or a gas fireplace. But, from the way you worded the description of your problem, I'm going to assume that it's electric. I'm also assuming that all the other features of the fireplace work, but the heater doesn' t. If that is the case, below is what the Owners Manual recommends doing.

5. Flame effect operates, but heater does not blow warm air

The TEMPERATURE button is a thermostat control for the heater. Each preset temperature setting has a different thermostat setting as shown to the right:

The heater will NOT activate if the room temperature is above the thermostat setting. If the ambient room temperature is 78° F the user will need to select Setting 3 in order for the heater to be activated. It is normal in warmer climates and in rooms with higher ambient temperatures for the heater to not activate on the lower settings due to the thermostat control. 5a. Try increasing the temperature setting. See drawing:

temp-control-fig.jpg 6. If unit heater does not function, but Power and Heater switches are in the "ON" position and thermostat is set on "HI" 6a. Turn all switches to the "OFF" position and unplug the unit from the wall outlet for 5 minutes. After 5 minutes plug the unit back into the wall outlet, and operate as normal.

The valve on my Thermoheat heater RMC FA50 will turn from the off position therefore I can not light or start the heater. It is stuck in the off position.

I'm assuming this is a gas heater valve? Typically, one must slightly depress the valve in order to turn it to pilot or on--a safety feature of nearly all gas appliances...

Is it ok to clamp the button in to keep a reddy heater (propane) lit? Will it hurt anything?

I would say "NO". Safety features are built into heaters for a reason. I assume you are talking about clamping the igniter button. What happens when the heater goes out and doesn't relight. I guessing gas will start to build up possibly getting to explosive levels. You need to find out what the problem is with the heater, not bypass safety features.

My heater runs for about 10 minutes then the flame cuts out and can't be turned on again till it cools down for half an hour...


Replace the flame sensor, if that does not fix the problem, check the thermostats, if it cuts off in ten minutes and then restarts when cooling down, then it is either flame sensor or thermostats.

Turns on but no heat

From what I saw when I googled you furnace it has a hot surface igniter. It only gets hot when it's time to light the furnace. You should be able to see it glowing red when the furnace is trying to light. The furnace has a safety feature which shuts the gas valve when it doesn't detect a flame to prevent gas build up in the furnace. There are other safety features also. If the draft inducer motor isn't running the gas valve won't open. Overheat switches some of which have to be reset manually. Adjust the thermostat until it calls for heat then observe what is or isn't happening in the furnace. It will go thru a purge cycle first. The draft inducer motor will run to do this. After the purge the hot surface igniter should get hot a glow, then the gas valve will open and the burner will light. Let me know what you find.
