The fan relay should isolate the 2 speeds hi & low use for cooling & heating. Normally closed should be the low speed, and normally open (closed when the relay is energized) should turn on the fan in high speed. Make sure the fan (isolation) relay is wired correctly.

SOURCE: Intertherm E1EH-015HA FURNACE no heat

Sounds like a downflow electric furnace? If so it sounds like you have 15kw worth of electric heat, you might have a defective heating sequencer, witch is what they call a dual on one plate.

SOURCE: Furnace Blower Motor Specs

That information is usually on the data plate on the furnace and on the motor itself. All you need to know now is the HP. Other than that a universal consolidator motor is an easy fix too. It can handle 1/6-1/3HP.

SOURCE: problem with furnace, air but no heat

the hot serface igniter may nead to be replaced again . if the is a lack of air
[ have this checked} getting to and frome the furnace it may be causing the furnace to cycle off the burner duing call for heat. it recycles back on and off untill the thermostat is saticfied. this means you are reusing the igniter more often the once a call for heat . therefore shorening it life expectancy.. make shure you are not blocking the air flows with over filtering ..whitch i have found to be the most common mistake . this and not changing or cleaning air filters often enough.

SOURCE: Electric furnace blows cold air before and after warm air.

It is normal. Your house has to go down a couple more degrees because the heat pump is not working. You can solve this by rewirng you thermostat. Take off the wire that goes to Y and tape off. Then take the wires that are marked w and e or w1 and put the wires to yellow. Do not run ac with it wired like this. If you need more information please post me back

Why does blower only operate manually?


Not wired correctly, if we are talking about a out side hot water furnace. The blower needs to be connected to a relay and transformer that connects to the inside thermostat.

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.

Fan will come on for heat(auto), but not for AC or set to ON


You have a blower relay in the furnace that's probably bad. In the heat mode the blower is on a temperature relay, in cooling mode the blower has to come on immediately so there is another relay for cooling. The green wire on the thermostat feeds that relay, so if you go to the furnace and shut the power off and find the green wire from the thermostat that feeds that relay and replace it, being careful to mark all the wires before removing them, also the relay terminals have numbers for identification.

1970's Rheem electric furnace


no the older rheems had a sequencer for the heat that turned on the blower at the same time that the heat strios are energized. so the first thing that you need to do is figure out the sequencer that is keeping the fan running and get it replaced.

Blower motor


follow the wires back from the motor to either the relay or the circuit board. normally a furnace has a board. check to see if there is any power leaving relay/board to the mtr. if it is a furnace you may need to push in the door saftey switch to get power to system. heat pump mtrs need 230 vlts furnaces 115vlts. If the power is going through to mtr properly than problem is either capacitor or mtr. capacitor can be checked for you by a local hvac supplier or buy a meter that can check it.
PLEASE rate or solution thanks. Brian S.
