Question about Heating & Cooling

No Heat and I'm Cold

I have a Rheem Furnace MD: RGDG-10EAMER, S/N DF50302 F4894 9075.

When I move the thermostat for heat the induction blower operates. The igniter false to glow in 25-30 secods, but the circulation fan operates too.

This problem appears intermittent over the last week. I've noticed the two (2) green lights without an amber when all works according to plan. When the aforementioned problem appears the two green light glow and so does the amber light. The amber lights illuminates after the greens do (2-3 sec). The amber light blinks four times, then on the fifth time the blinking become more rapid.

Thanks!!!

Do you have the code reference on your furnace door? If so what does it say? The furnace has locked itself out, and we need to determine what in the world it needs..

My rheem gas furnace got red button that keeps griping what can I do.


The red button that keeps tripping is probably the rollout sensor just above the burner assembly. When this rollout starts tripping, it means your flue gasses are not being drawn out by the induction fan motor. If your furnace is a few years old, the fan blade has probably rusted out and is not moving the flue gas. You will need to get a new induction fan motor. While you are checking the induction fan motor, it is a good idea with everything torn apart to check the condition of your heat exchanger. When the induction fan blade rusts out, it is a good indicator the heat exchanger may need replacing also. So do yourself and favor and check it out for rusted out welds and the like. You will probably need an experienced hvac tech to make the furnace repair.
Hope this helps.

Carrier troubleshooting furnace


If the thermostat isn't selected for "FAN" then the relay is stuck. In heat mode the thermostat opens the gas valve and starts the igniter and the induction motor. If the induction fan isn't running, the flame will stop.

Rheem rgph 10eamer 8 yrs old ...blower motor wont stop running...i had the a/c on....decided to ck the furnace ...switched to heat...blower still running....no spark from direct spark...


Hi Richard. The switch they are talking about has a small tube coming from the induction blower housing straight to the switch. The best way to test it is to blow and **** on the tube while it is still connected to the switch. You should hear small clicking sounds coming from the switch, if not than it needs to be replaced. Another thing to try is a small wire or paperclip through the small opening where the tube came off. Sometimes this gets clogged and causes the same issue. Other than that, it can be a blocked flue or the inductive blower motor itself is not working properly. Hope this helps and good luck!

RHEEM OIL FURNACE MODEL ROBD 067 LBEA BLOWER


You will likely need to install an isolation relay in the W circuit from the thermostat. Some thermostats rob a small current through the W circuit to power the thermostat. This small current can be enough to start the fan circuit timer. You can test this by disconnecting W at the furnace and allowing the timer to shut down. If the fan shuts off with the W disconnected you can install a simple relay.

The relay coil will be connected to Common on one side and the W from the thermostat to the other. Then you will run a wire from R on the furnace to the relay and from the N.O. Contacts to the W terminal on the furnace. This will kill that signal that is starting the timer and the W can steal it's power through the coil back to common.

Rheem RHQA Heater:Blower works but no heat.


Is there a setting on the thermostat for Auto or Fan? If so, make sure it is in the Auto setting. You will have a contactor that turns on the elements and a relay for the fan. Follow the wiring diagram to see which relay energizes the fan then unplug it to see if the fan stops.

Rheem gas furnace blower unit not working properly


look at circuit board and follow wires that come from fan motor, if this is a standard motor black is high and it will be going to a prong that says cool, red is low and it will go to heat, you will have a yellow and a blue that are "parked" remove red park it were the blue is and put blue on heat, if this is a variable speed motor you will have to set dip switches via your equipment manual
