Ee 12 code

Hi alaskasteve,

My business is Laser Heating Service in the North Pole/Fairbanks area of Alaska. EE12 is the error code for overheating. Most likely you have a Laser 30 giving you this error code. The most common reason for the EE12 error code is that the Toyo is not getting enough air circulation across the heat exchanger and causing it to overheat. Look at the back of your Toyo where the black frame around the circulating fan and flue pipe is. You will see a screen that slides in a slot at the back of the Toyo. Slide the screen out and clean it. If you have a smoker or the Toyo is in a kitchen area where it collects nicotine or grease then you may need to clean it with hot water, detergent, or 409 Cleaner to get the sticky residue off that the dust fuzz collects on and clog your screen. EE12 can be caused by a couple other issues, but they are more rare. Try this first and let me know if it works! toyotechnician

RINNAI 556f blinks 60-76 error code. Can't find that in the book!

Page 40. You are right it isn't in the book. https://media.rinnai.us/salsify_asset/s-e598de00-1d57-420c-847e-c40af41a7a87/RHFE-556%20FTRA%20Installation%20and%20Operation%20Manual.pdf Just guesses with a targeted search query. 'Combustion Failure'. https://www.google.com/search?q=RINNAI+556f+%2260-76%22+error No matter anyway, it is a gas appliance and can only be worked on by a certified gas registered technician. You can try a power cycle reset. Disconnect all mains power and wait 5 minutes, press and hold the power button for 20 seconds, let go and power back up. Wait 2 minutes for a self test to complete. ..

Glo-Warm heater shuts off

I have had the same problem and I think I fixed it. Near the pilot light you have the part that shots the spark (electric ingitor?) behind it is another brass part which I beleive is flame sensor, what I did to fix it is losen the philips screw that holds the two in place then pushed the flame sensor higher so the pilot light hits it more, then just tighten it back up. I hope it helps....

My Rinnai energysaver 557ftr is showing error code 12. It will turn on, the fan works and it makes a bubbling noise and the flame lights but then immediately goes out and the heater stops.

It is a Gas Appliance and needs repair by a qualified gas registered technician. It is a generic code for 'no flame'.

How do I turn of radiators for summer?

Step 1: Also known as a manual valve, find the non-thermostatic valve on the left or right side at the bottom of your radiator. The other valve on the radiator will be fixed or will be capped. Step 2: To turn your radiator off, turn the valve clockwise as far as it will go.

Rinnai RC-329ac not coming ON although the power button is OK

It sounds like there might be an issue with the power button on your Rinnai RC-329ac heater. Based on your description, it appears that the power button is not functioning properly and the heater can only be turned on by using the "good night" button. There could be a few reasons for this. One possibility is that the power button is physically damaged or malfunctioning and needs to be replaced. Another possibility is that there's a problem with the control board, which is responsible for managing the heater's functions. To troubleshoot this issue, I would recommend checking the following:
  • Check the power button to make sure it's not physically damaged or jammed.
  • Check the control board for any visible damage or malfunction.
  • Make sure the wiring connections are secure and not loose.
If you are not comfortable working on these issues, it's best to call for professional help as it may require a technician with experience in Rinnai RC-329ac to properly diagnose and fix the problem.

Rinnai EnergySaver ES38 Gas Fired Direct Vent Wall Furnace. It will not turn on. Does that mean the computer board is messed up?

Question edited for spelling of maker and full 'what it is'. Question moved from Cars and Trucks. Doesn't sound good is nothing turns on, but if you have power, it may be safety devices operating. There is a troubleshooting section in the manual. https://www.manualslib.com/manual/141160/Rinnai-Energysaver-Es38.html?page=13 Video help https://www.google.com/search?q=Rinnai+ES38+not+turning+on ..
