Question about Dayton Heating & Cooling

1 Answer

I have a Dayton Model 3E341A Heater and cannot get it to produce heat. The fan works but no heat. I purchased this unit used and thought it worked. I opened the botom and saw the electrical connection area. One thing I saw was where it said summer fan. I am wondering if I need to change something here to make the heat work. Can you help me. I was looking for a manual but was unable to locate.

Hi, I can't find anything with the model # you have listed. Is this a torpedo type heater? If so, remove the top of the heater and turn the fan by hand. It should be fairly easy to turn. Next with the top still off, turn the heater on and make sure the igniter is working. If that is OK then use a flash light to check for fuel spraying from the nozzle. Watch out for the fan. If it isn't, check the fuel nozzle for blockage. If you remove it and hold it up to a light, you should be able to see light through the hole. If not, use a small wire or something to remove the blockage. If that is OK, check the fuel filter. You may be able to clean it or you can replace it if necessary. If this doesn't get it, you need to check the air pressure going to the fuel nozzle. On the back of the fan motor there is a filter cover with 2 plugs in it. One of the plugs has a hole in the center and is used to adjust the air pressure. The other plug is where you can install a pressure guage to check the pressure. I can't tell you what the pressure should be because I can't find anything with your model #. It may, however, be listed on the data label on your heater.
If your heater isn't a torpedo type heater, none of this will make any sense. Let me know what type it is if it isn't the torpedo type.

    Do you care to give me a little feedback on your problem? I may not get it on the first try but that is why it is called troubleshooting.

Fan will not come on unless thermostat is on "fan on". When it's on auto, the fan does not come on

Here is my best shot! I THINK there must be a THERMOSTAT that is defective?

I tried and tried to find a schematic or diagram for your heater without luck.

IF there is a AC connector ~ disconnect it...
Pull your panels off one-at-a-time looking for a DIAGRAM and anything that LOOKS like a thermostat? Hint: It usually has only 2 wires.

I am fairly sure you WILL find one and if so ~ THAT thermostat would be my first suspect! Please let me know how this goes?

Dayton gas furnace model 3e385 works and lights but as soon as fan comes on the unit shuts off and lights again wondering what was wrong

Check heat exchanger for cracks or holes which will cause the fan to blow out the flames. The flame sensor on the pilot or burners has to be in constant contact with flame to operate normally. If the flame is put out by a cracked exchanger the exchanger or furnace needs to be replaced.

I have a Dayton 3VU32 heater. The fan does not turn when the switch is on fan or the other 2 heat settings. The heater does produce heat. Is there a solution, are parts available and where?

Dayton is a Graingers brand. Please contact Graingers at the web site below to see if parts are available. It may be cheaper to just buy a new heater. Hope this helped you...Jim

Dayton heater Model 2E400. Does the fan draw the air in and than blow the heated air out of the botton of the unit? Does fan turn CCW or CC.

yes, you have the direction of flow correct. The rotation of the fan will be marked on the motor of the fan

My dayton NG heater fan will not shut off properly

Sounds like a bad fan switch. The switch is located on the heat exchanger and is 110 volt bi-metal switch. Follow the wires from the blower going back to the heatexchanger. Graingers can get you a new switch if you give them your model number.

I've got a Dayton 3E369 Unit heater. The electric

Sounds like it has a bad fan switch wich is no more than a small circular bi-metal switch that expands when heated closing a switch. Get a parts breakdown off the net. I am sure you could find the switch in your area and replace it yourself.

My Dayton garage heater model 2E636B does not heat up.

These heaters are the same as the marley heater, the element never gets red hot. the unit is set up so the fan kicks on after the element has heated to a certain temp and turns off after the element has cooled. It is common for these heater fans to cycle on and off quite often untill the air temp reaches about 55 degrees and then will operate normaly. If the fan still cycles too often you may have to replace the fan control and high limit switch. These are not very expensive and easy to replace yourself. they arte usualy attached to the back of the element with clips. The luke warm air is what these units put out. I have an equivelent to the dayton G73 and it heats a 24' X 30' garrage all winter in central Minnesota.

Dayton 3E227A Heating Cycle

The sensor for the thermostat is probably going bad or has bad connections. It is (or thinks it is) heating up fast and therefore shuts of the heater.
