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 ..

Hello, I just got an older natural gas direct

Hi John, it should say on the front or somewhere near the control panel what model it is. If you could email a good picture of it to me I might be able to tell. If it is a Monitor heater, go to www.monitor.com or if it is a Toyostove heater go to www.toyostove.com and you can download an owners manual. The most recent models of Monitor gas heater are the GF 3800 and GF 1800. The older one is the GF 500. You can send a picture to [email protected]

Sounds like your igniter may have burned out. You can test the igniter with an ohmmeter. You can also check for voltage on the circuit board where the igniter connects. Don't try to start it again until you check the igniter because unburnt kerosene will just keep building up in the burner. Let me know if you need more help.

Rinnai Energy saver 1001f not kicking back on

I would suggest that your landlord is responsible for heating as you rent and must ensure the heating works properly, especially when using gas. Contanct a Rinna service agent and have it serviced at your landlords expense.

Rinnai 1004 F Error Code 11

Code 11 is that the unit is trying to light but does not sense a flame after 5 seconds. Usually means you have run out of gas if you are bottled gas. Check your bottles are turned on if you are on LPG, you might need to change over manually. Have you anything else on gas?

Rinnai 556F Not Exactly and "Energy Saver"...

Raise the thermistor. It is a black rubber probe located on the back of the heater close to the coldest spot in your home, the floor. Raise it a few inches. To do this you will need to unhook it from its holder and open the front of the heater to unravel the extra length of yellow wire.

Rinnai 1004 - Temp on thermostat reads 10 deg cooler than actual, keeps running

Behind the unit near the floor level, is a yellow wire with a black bulb at the end. This is the actual sensor for returning air. If there is cool air infiltrating the area where it is located, it will keep the unit running until the return air reaches temperature. You could also have a bad sensor but highly unlikely. Make sure there is no air infiltration influencing the sensor. Also, you can unclip the sensor and pull out a few more inches of wire to locate it higher up away from the floor. Tie it up with a wire tie.

Rinnai it testing a remote thermostat but as of yet, there is no plans to offer one.

Rinnai 1004 heats to a temp 4 degrees higher than set temp, adjustment?

You can adjust the position of the room air sensor found on the back of the unit between the heater and the wall. It is a black rubber bulb with yellow wires. There is a few inches of extra wire you can extend higher to get a more accurate reading of room air. While you are back there, check for drafts that will give you false readings.

I have a Rinnai model

You probably don' need to start with the thermocouple. If the pilot is burning with a yellow tip and is curled away from the thermocouple. What you have is a dirty pilot. The heater thinks you have a low oxygen level because of lint or bug in the mixing chamber. With the pilot off, take a drinking straw and blow backwards thru the pilot opening. Then try again.

556 wt rinnai wall heater

PF codes tend to signal a power failure. But if you don't have power it shouldn't have flame either. A red flame tends to be lack of air flow. Check your breaker panel to ensure the breaker isn't tripped. Turn it off, wait a few seconds and turn it back on. Sometimes they may be tripped but not look like it. Also, if the power is fine and your getting a red flame, check your flue pipe termination points to ensure they aren't blocked.

I have an MPI monitor heater model gf 1800. It keeps flashing E17. why?

My GF 1800 was flashing the e17 code as salenski_mar said.If all is clear around vent pipe, sufficient fuel in tank,ect. take the front cover off the unit,2 sheet metal screws on bottom side left and right(remove power first)on the left side of my unit there is a round black barell shaped container called a heat exchanger.Located about halfway up a small panel with 2 white tube shaped wires going into it.remove 4 screws on this panel and remove the panel. There are 3 electrodes here . carefully clean these with a rag or fine sandpaper. Reassemble and retry the heater.I watched a heating tech do this to my unit and charge me $75.00 last year.Did it again this year and I saved a service call.Actualy I believe he used a $20.00 bill instead of sandpaper but clean the flame sensor and it may work.worth a try.

Rinnai Heater - error message "12"

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.
