Re: Rinnai RHFE 1004F Error code 49

A 49 error code is caused by the pressure switch either not proving or a bad component. Check the hose attached from the plastic elbow located behind the heater going to a small square pressure switch found inside the heater. It may have come loose or a mouse may have taken a bite out of it. Also while you are behind the heater, pull off the hose that looks like a vacuum cleaner hose and run the heater with it unattached. If it runs, you have a blockage in the vent. If not, take a flashlight and go outside to the vent. Look down the center pipe for any obstructions. If it still does not work, you may need a new pressure switch.

While the front panel is off the heater, cycle the heater to attempt a start. You want to make sure the blower turns. If it does not, check the wire connections to it. You may be looking at a bad blower. If it is turning but still does not start, we are looking at a bad pressure switch.

Let me know what you find, I may have a switch or blower motor that you can purchase.

My Rinnai 1004F giving me error code 99

This fusible link may be open. Try jumpering the two leads and see if the unit operates. If it does replace the fusible link. Do not operate the unit without the fusible link for an extended period. It is a safety device and is there for a reason. Hope this helps.

You can get any error code that may be stored by pressing on the Economy button and the UP and Down arrows all at the same time and hold for 5 or 6 seconds. This may get you a start on what may be the problem. Post them when you get them. If you do not get any error codes, remove the right side panel closest to the wall and look for a small black rubber bulb. That is the thermostat for the unit. If you hold it with your fingers, it should show a higher temp. I am afraid that you are going to need a technician who is familiar with Rinnai heaters if you can't get it going.

Do you get an error code? 11. 12 68, 72, etc. Does the combustion motor come on. You should be able to hear it. Is the exhaust and air pipe clear? Is the air hose hooked to the back of the stove?

Error code 12

Three main causes.

Short circuit on the low voltage side of the wiring (12V) This will show as an immeadiate error code 12 befoe the thing even tries to light.

Faulty earth on the low voltage side shows same as above.

A faulty gas regulator or partial blockage of gas supply that allows the unit to fire, but will not maintain sufficient gas supply to keep it alight. This will happen after it has lit, maybe erratically with the occasional error code 11 if you try and re-light immeadiately.

Error code 11 on my rinnai

A code 11 also means that it might not be getting any gas. On thr right side of the unit you will find a small door. open it up and make sure the valve is in the open position. If it is, you should contact your gas company to come and diagnose what is going on. The Rinnai is not a do it yourself fix it type of heater.
