I have cleaned out and blown out what ever I could without disassembling the unit. The unit works fine until it runs for a while and then the burner flares up and then the unit begins to shut down. I even removed the burner window and blew that out with a compressor. Any ideas?

Re: Monitor2400 heating problem error message E14
I would not use an air compressor to blow inside the unit. You could do more harm than good. E14 means the stove lit normal and ran normal for a while and then quit. I would look at the fuel system. Low fuel, no fuel, dirty filter on tank and stove. After that look at the flame sensor for a small amount of carbon. You will need a gasket when you put it back together. Make sure the exhaust pipe is free of ice and snow. Beyond that you will need to get into the burner. For that you will need a manual and parts.
You may be getting carbon build up where the flame us causing the heater to not sense a flmae. I have a Toyo. I don't know how close the Monitors are to them. It may be time to have the heater cleaned, or get ahold of a manual, and new gaskets, and clean it yourself, although it is a bit nippy right now to do that.

on start up the clicking noise is normal as well as knocking noise ....one important item with fan , if the fan was removed cleaned and then reinstalled with power to unit could have ruined the fan and it will have to be replaced..... Cant tell you why is wasn't firing before with no codes...other than flow sensor not working( most likey stopped with sand fragments or trash) the flow sensor detects hot water demand and ignites heater and if clogged it will not light up but doesn't give error code and the water running through hot side will be cold..... flow sensor is a turbine that detects water movement and lets heater light..... may want to get serviceman to check this out and clean turbine.... hope this helps...
Does this problem happen when the temperature is below 30 degrees? When it gets about that cold outside, the air outside is too cold for the heat pump to "steal" heat from. On the thermostat you'll find a switch labeled aux or emergency heat. Turning this switch on will operate a traditional coil heater inside the system, providing you with heat. The only downfall to this is that it uses more energy to heat this way. Try turning the fan switch from "auto" to "on". If the fan comes on, then we can rule that out. If the aux heat switch is NOT on, set the thermostat such that the system will try to heat. If the outside unit is running, the problem is either it being too cold like I said earlier, or there's a problem with the heat pump's mechanical system that needs to be serviced by a professional. If the outside unit doesn't run but it should be, check it's breakers at the panel, the breaker inside the electrical box that feeds it, and look to see if there's a reset button on the unit itself. Finally, check the air handler (part of the system inside with the fan in it) to see if there's any circuit breakers or fuses on this unit. Make sure they're not tripped/blown. If none of this helps, you definitely want to get a pro to work on your system.
An EE 2 message can mean 2 things
Ignition never happened or unit did not sense flame
You should see the Igniter glow through the peep window during pre-heat, easy er to see with front cover off.
If you do see a glow and flame happens, but unit still errors out.
Try to clean flame rod sensor.
Single white wire going to burner pot. (pull straight down)
2 screws hold a plate
Turn sensor to 3 o'clock or 9 o'clock position
pull sensor out easily
Clean sensor with sandpaper- down to shiny metal
The 5840 has a problem with dust getting on the heater element and turning itself off after 2 minutes running. HERE IS THE FIX. Unplug the unit from the AC outlet, Then using a can of dusting air ( the kind you use to clean a computer key board) aim the compressed air INTO the middle louver of the upper adjustable heater vent and blow out the dust that has gotten on the heater element. ( You are actually blowing into the unit, clearing off the lint/dust that has gotten on the backside of the heater element that you can not see without openning the entire case).You can see the front of the heater element inside the louvers, It's the shinny metal part that looks like a small radiator.It sits behind the middle louver. After blowing out the dust, shake the entire unit to allow the dust to settle to the bottom of the case. Using a vacum cleaner try to vacum out any dust from the LOWER FRONT intake. Once the dust has been blown OFF the heater element, the unit will work just as new and not shut itself down!
I cleaned the fuel screen located on the unit and replaced the filter on the external fuel tank. The external filter can freeze if it accumulates enough water and the temp is cold enough, or it can just get full of debris. I also unplugged the 2400 for 30 min to let the factory preset settings come back. Filter(s) caused the e14 error, preset settings cured the e13 error caused by me fooling with the start stop function so much. Thanks for the help!
An error code of 12 on your heater means a flame failure has occured. It could be the following: Flame Rod dirty, Obstruction in burner, improper gas pressure, or a bad ignitor board. I am suggesting you get a technician who is familiar with Rinnai products to check out the above items.
It could be many things, but the first thing to check is if the heating element is good. You'll have to (carefully) disassemble the unit. Another thing that is possible, depending on the unit, is that the fuse is blown on the internal circuitry of the oil heater. A third possibility is that the thermostat is defective or has a short circuit. If you are not comfortable monkeying around in the guts of the unit, call the company and ask what service options are available.
