Question about Rinnai EnergySaver 556 Air Conditioner

No spark to ignite

When I turn it on, my rinnai doesn't heat up. The motor runs for 10 seconds or so, then it shuts off and a red light blinks. Any ideas?

thanks.

I have a Rheem furnace rglh-10nbrjr that motor runs but flame does not light. If I turn up thermostat, the fan comes on and I hear a click after 10 or 15 seconds. I see no spark or anything from electronic...


Hi, you shouldn't smell any gas until the pilot flame is etablished. The sequence of operation is the small inducer motor will start on a call for heat, Then on the motor you should have a poly type tube, clear, that runs over to a pressure switch. It is a round silver part that the hose connects to, The pressure from motor closes a set of contacts and you will hear a click. This is telling the electronic ignition to start to spark and light the pilot or hot surface ignitor, which ever you have. If you have no spark and the pressure switch is closed, you have a faulty ignitor board or module. To check the switch, it will have 2 wires going to it. Just take a piece of insulated wire and touch across the 2 terminals. It should fire up. If not, the module or board, ignitor has failed. You will need to take all of the numbers from it amd go to a appliance parts house to get a new one. Don't forget how it wires back in, or you will have more problems.

I have a newer tappan heater and get 4 blinks on led for error code the unit starts up fine and has flame but flame goes off when blower kicks on


Problem: Your furnace will not ignite the gas to produce heat for your home. When a furnace has a bad ignitor what I see most of the time is the following sequence of operation:


1. Thermostat calls for heat. 2. Draft inducer motor starts. 3. Pressure switch attached by a small plastic or rubber tube senses the negative pressure produced by the draft inducer and closes. 4. Draft inducer runs for 30 seconds to a minute before you hear a gas hissing sound. The ignitor did not glow, the flame sensor (a small metal probe about 1/8" in diameter, with a white porcelain base) does not sense the flame, so after 8 to 10 seconds the hissing sounds stops with no ignition of gas to heat your home. Your furnace shuts down and goes into a lock out condition until you turn your power switch back off and on again. Then the sequence starts all over again with no ignition of the gas. Solution: You probably need to purchase and install a new ignitor. I would suggest that you inspect your ignitor closely for cracks. Make sure you do not touch the ignitor with your bare hands. If you do not visually see a crack, then you could have a furnace control board problem or a limit, rollout switch problem. The furnace's control board might not be supplying the voltage to the ignitor. If your furnace lights and the gas stays on for 8 to 10 seconds, then shuts right back off, then you need to clean your flame sensor with light sand paper or steel wool. You might need a new flame sensor, but most of the time they can be cleaned an will work well after cleaning.

My tank says I have 32 gallons left but the heater won't work (rinnai 556f). It turns on for about 15 seconds and the light on the power button turns red and starts blinking. What does this mean?


If you hold down the economy button and the up and down arrow buttons for 5 seconds the unit will start an error code display. Get a helper and yell out the numbers when they start blinking. Post the error codes and we can help you

You are half-way right, to light the pilot, light it and push down the red button and hold it for at ----least2-minutes-- till the flame heats up the pin (thermocouple- which fire-thermocouple metal makes electricity which sends it to the gas valve and says ,OK GAS VALVE,I'VE GOT A PILOT FLAME SO OPEN UP THE MAIN GAS VALVE!

Ductless heater shutting down


There is a small wiring harness that goes from the main board down to the sparker board at the very bottom of the heater. Disconnect this harness and reconnect making sure all pins and contacts make good connection. If it continues, replace the wire harness. Also make sure the outlet that the heater is plugged into is a grounded outlet. Stray voltage can interrupt the thinking of this unit.

If all connections are good and the unit is grounded, you are probably looking at replacing the sparker board. I do have these parts and would be more than happy to send them to you for a donation.
