Re: Centralized gas heater


Pls check the following,

1) Check the NamePlate of the units base to input Power supply voltage (when the voltage is low your unit hard to start its so hear sound noise before to start).
2) Check the wiring connection if this is inverted.
3) Check the connector wire to Compressor/F.m.may be loose.

If this not solve go to the nearest repair shop to check the compressor if this is internal problem.

Thanks & best regards,

Clicking noise Rinnai Avenger Gas heater

Is sounds like it could be the automatic ignition. If the sound only happens when you are pressing or turning the knob, I would say that is all that it is. Most gas heaters have an ignition switch under the knob. This triggers the ignition to try and spark. light the gas when the knob is depressed.

Have a rinnae royal gas lok heater. Cant start it after gas was shut off. How do you get the ignition to work and start the pilot light again

When the gas was turned OFF, air got in the line(s) and created an air pocket. This air will need to purged from the system, before the heater will light. It only the shutoff valve on the gas line to the heater was turned OFF, it will be easier to purge. If your Rinnai heater has manual ignition rather than electronic ignition. Holding the control down in the Pilot position, will eventually purge the air. If you have electronic ignition, continually trying to light the unit will do the same thing, but take longer to accomplish. Consulting your Rinnai will also help you with this situation.

Hope this helps you and thanks for choosing FixYa.

How do I Turn the heat on ?

It's hard to answer that question because there are so many variables. First I would look at the thermostat and see what manual settings are available. If it's a non programable there should be a switch that goes from heat to cool,one position for fan on , one for off, and one for auto. Set the heat/cool switch to heat. the fan on ,off and auto to auto. Then turn thermostat control up so it's above surrounding temperature.This should cause the heater to come on. If that doesn't work you may have problems with heater or thermostat. If it a programable t-stat I will need more information,such as name brand,model,etc. Hope this helps. Thanks.

Heater not consistantly turning on

This is an interesting problem. In the beginning of your statement you say that the "heater" does not turn on consistantly. My first couple of thoughts are, 1. What is your fuel source? 2. How is the furnace vented? (chimney, sidewall) With these questions answered we might be able to get to the bottom of the issue. But just for giggles lets continue to make observations. A "ventilation fan" does not really give enough information. There is a "powerventer" which allows you to vent an appliance out the side of a house. There are booster fans, which are sometimes installed in long lengths of "vent" pipes to help the chimney maintain a proper draft, and on gas appliances (newer) there is a inducer motor, which pushes the gases out of the residence. The way that the powerventer is wired is in a way that will not allow the burner to fire unless it first proves that venter is creating a draft. Booster fans usually are just wired in parallel with the burner circuit, and will run anytime there is a call for heat. Inducer motors (on gas furnaces only) will not cause this issue. With all this being said, I would find it highly unlikely that the problem is/was both in the board and the draft. If in fact you are pulling such a strong draft that you are "sucking" the flame out, then I don't think you need the "ventilation" fan. Hope this helps

I have a new home 1 yr and when the furnace kicks in, I am assuming the fan it makes a noise but as soon as the heat starts the noise is gone, could this be the furnace blower

Check by turning the unit off and turn the fan to on. Do you hear the noise now? The noise your hearing could be coming from your combustion fan assembly instead. Newer furnaces have a in-shot burner and are nosier than the old style of heater.

I've got a Danby DPAC 8399-4 portable heater/air conditioner. We usually use it as an A/C but we're trying to use the heater for the winter; we just brought it out of the closet. The fan barely works (and...

Check for obstructuions in the fan housing that may be hitting the fan blade, causing the noise and improper air flow.

Improper air flow will cause the uniot to overheat quickly and it will shut down on its high temperature limit switch.

You may also have a bad fan. Bad bearings will make a bad noise as well. Thios will cause the same symptoms described above.

Check for abstructions, if you can find one, remove it, if not replace the fan. You can usually reset the limit by simply turning off power and turning it back on after 10 min.

Check the draft inducer motor for any partial blockages or dibri.

I've seen sticks, birds nest particles and pieces of deteriorating fan blades (squirrel cage type fans) cause this.

You might also find that the inducer motors bearing are going.

If its a loud vibrating grinding type noise, I'd suspect bearings or missing pieces of the blades. (unbalanced)
If it's a clanking type noise I'd suspect loose items hitting the fan.

The inducer motor will only operate right before and during burner operation, while the blower motor can operate at any time depending on your setting.

Janitrol/Goodman GMP075-3 Draft Inducer Fan Won't come on

most forced draft fans are powered by 120 volts . close to the fan is usually a plug that unsnaps. create a call for heat after turning off to clear safetys and see if your getting 120 to fan on initial call for heat. if you are then fan draft motor is bad, usually sold as an entire assembly replace exact as it came out. sequence of operation is..... stat calls for heat via common and white wire to furnace , 24 volts. ......board sences call and sends 120 volts to forced draft ........ motor runs and creates pressure on proofing switch,....... switch closes 24 to board and tells it draft fan is on......... board then energizes ignitor,....... after ignitior glows gas valve is opened and burner lights ........ either ignitor or seperate sensor rod tells board the burner lit........ and a few minutes later the fan comes on and hot air is blown out. if a step is missed or doesn't proof the furnace either trys up to three times to light or locks out. turning off power usually resets safetys and it will resume attempts to lite normally.
