Question about Dayton Heating & Cooling

2 Answers

Hi, I replaced the heat sensor for pilot light with an after market from Big R and now when I turn the dayton unit on, it makes a sonic boom before it lights... not a good thing right? but it does blow heat and runs good after that. So my question is does it have to have a sensor unit just for dayton? Or is there another problem like heat exchange cracked ? Thanks, Phil

I would inspect the regulator. It seems it doesn't let the flow of gas seep out slowly when it ignites

You probably have rusted burners. Remove them and wire brush them . Look for a split in one or blockage. Blow em out with shop air. Gas is pooling up before ignition. Rusted burners Seen it.

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.

Dayton3e368a pilot lights but burners do not come on. Heat rod was replaced last year. Heater is in a greenhouse


Most heaters has a pilot proving sensor of one type or another, it will be in direct contact with the pilot flame to prove that the pilot is lit and then will allow for the main gas to the burners to open. If the proving device has failed then it needs replaced.

How to light pilot on Dayton furnace and then start furnace


If this is a standing pilot system, turn the gas valve to pilot position. push in the knob & hold while lighting pilot...keeping holding knob down for a minute... this will pick & hold the gas valve. Let go of the knob & see if the pilot stays lit, if it does, then turn the knob to on position & the furnace should start if there is a call for heat from the thermostat

Have a dayton 3F405D propane greenhouse heater don't know where to light the pilot light.


Find where the gas line connects to the gas valve on the back of the heater, from the gas valve, follow a small aluminum tube going into the back of the heater. There may be a removable door to access the pilot assembly. If there is no aluminum tube, the unit has electronic ignition and no pilot lite. Turn the gas knob to off, then to pilot. Hold the gas valve in and with a long match or gas grill lighter, light the pilot. Continue to hold the knob in for about 30 seconds. After that, release the knob and check to make sure the pilot stays lit. If so, rotate the knob to ON. The thermostat will kick the burners on.

Have a Dayton 600,000 BTU and it has a delayed ignition. It fills up with fuel before it lights. When it does light there is a big cloud of smoke. Any suggestions on why it does this.


For that big of unit I would add at least two more pilot lights. Try to position them so they are equal distance from existing pilot.You can buy pilot light assemblies,pilot light tubing,andfitting at most H.V.A.C. supply centers. Hope this helps you. Thanks

Pilot light goes out when turning on the thermostat


Check your thermocoupling to make sure that it is sensing flame. You can tell if it is good or bad by the white on the tip of the flame sensor. The other problem would be a blocked or closed flue pipe. Make sure that the cap is not smashed down on the pipe on your roof

Dayton 3e239e looking for operation manual


Normally you turn the gas valve to the pilot position, light the pilot, hold down the gas valve knob for 30-40 seconds and release. If the pilot will not stay lit replace the thermocouple. These are available ay Home Depot.

Dayton Infrared natural gas heater ignition/flame sensor


Yes, the flame sensor is part of the intermittent pilot assembly. Check the following: make sure all grounding wires are secure and no corrosion is built up on them. Clean or replace the pilot assembly, also clean out the orifice with a very small drill. Make sure the sensor is in the flame and make sure the pilot tube is not leaking gas reducing the gas pressure at the pilot.

If it continues, you will have to replace the ignition control.
