Where is the summer/winter switch located on Dayton Fuel Trimmer furnace model 3E438A.?


The typical 'summer/winter' switch is an added switch associated with OLD heating systems back in the 50's and 60's before central air conditioning became common in homes. I doubt that your new furnace had one installed because you can accomplish the same thing by switching the fan on at the thermostat sub-base. That is, of course, providing you have a subbase with 'fan-on-auto' on it.

I am having trouble getting my Dayton Portable Oil fired Heater Model # 2E218E to keep running.


May be the primary control if you already replaced the photocell. Make sure the photocell is in direct line of sight with the flame.

Will the fan run with the fan switch in the ON position? as opposed to the AUTO position. If so the temperature or time delay or motor may be bad.
the fan switch operates the fan relay that controls high/cooling speed, heat speed is a time or temp delay.

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

Is the front of the fuel powered heater supposed to glow red?


Hi, and the answer is yes. All fuel powered type heaters will glow red, or bright orange. Example, a space heater that runs on #2 fuel oil, natural gas, gas, kerosene, ect. will glow this way, so do not be alarmed. This is normal.

Furnace will not respond to thermostat call for heat. Thermostat has been replaced with no effect. Have been informed it may thermocouple problem. Please advise. Thank you.


there's no thermocouple.there is many other safeties.hears what happens when you turn on;.1 draft inducer motor comes on. if all is ok with vent,then; 2 ignightor turns on .after a few seconds; 3 gas valve turns on if all limit switches and inducer switch are closed;.4 flame sensor checks for flame.after short delay fan comes on.if any safety switch is open theres no heat.look in little window and count red blinking light.theres a chart inside cover that will tell you whats wrong.some times theres water in tube going from draft inducer to diafram switch.the limits around fire box can be reset by pushing button in center.if theres no red light then low voltage transformer may be bad theres also a little fuse on board.if its blown you need to find out why.also any of these parts can go bad at any time.good luck

Burner lights but limit switch will not turn fan on automatically. the burner will shut down if i don't run fan manually. is it the limit switch?


Hi, Yes, you have the answer to you're problem. Now, I don't no if you have just a high limit, or a combination Limit control? I will go with the combination fan control as when they go bad, they stick in the closed position and they have normally open contacts. When the heat exchanger starts to heat on a call for heat, there is a dial on the fan control with temp. settings on it , and it will start to rotate as the heat gets higher. When it reaches its set fan on temp, it with start the fan.We no the fan works so the blower is good, so it shuts the burners down on you're high limit temp. which is factory set to about 250*F. When you turn The t-stat from auto to on in the fan side, that solves the problem temp, only. You will need to R & R the Fan control. If you need some direction on doing this please let me know and if it is a Honeywell auto/on type that is rectangular in looks, and if you remove the cover you will see the temp. dial with arrows on it. Thank you.
Best of Luck, and Sincerely,

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.

Vulcan oil heater


1. Check electricity is on.
2. Check oil is in the tank and valve turned on.
3. Switch the fan off at the bottom left hand corner.
4. Switch oil knob to No.1.
5. Set Air knob to No.3.
6. Operate re set button (right hand corner of heater under settings dial). Either press in until it clicks or if the pull out version pull out until it clicks.

Wait - ignition should take place in a few minutes and flames will appear on the left of the burner under the radiants.

You should get occasional yellow crests above the pure blue flame just visible below the top row of burner holes under the radiants.

After the red warning light goes out you can adjust to higher settings.

The radiants do not glow on low setting.

You can adjust the heater on to higher settings but this should be done gradually - no more than 2 settings at a time.

Some warnings:

* The unit must be correctly earthed.
* Do not use anything except heater oil.
* Never attempt to re-light the heater when it is hot.
* If the red light does not appear when the oil knob is switched on, immediately turn the oil knob off. Reasons include: Heater is too hot; Electric plug turned off; failure of ignition system.

Good luck - no responsibility taken for the advice (but it is largely copied from my Vulcan heaters instruction manual which I still have (installed in 1967).
