Question about Heating & Cooling

1 Answer

Rv furnace stopped working

Furnace went through heating cycle, stopped & then fan started up again for about 30 seconds. Twenty minutes later, furnace fired up & ran for 2 minutes, stopped, re-fired & ran for 6 minutes & then stopped. Twenty minutes later I heard thermostat click on & the furnace clicked, but nothing happened. I turned thermostat off. Turned it back on & heard the click from the furnace, but nothing happened. Propane tank is full. Unit is about 3 years old & about 1 year ago I had to have the motor replaced (rebuilt). Does it sound like the motor again, or is it something else (motherboard)? Your help will be greatly appreciated. Thank You, Gary Scott

Quick call the installer to see if it is still under warranty. There is something wrong if the motor is being replaced every other year. Most of the motors should be lubed with fan turbine oil and not 3 in 1, nor detergent containing oils. If the wrong oil is used, the bearings will go south in 1 to 2 years.

Sounds like your repair man ripped you off. He should have stood behind his work.
1. I would try to clean the flame sensor located just below the burners. It is connected to "one" wire (Not the two wire) clean rod with sandpaper.
2. The old and thermostat could have a had a bad heat anticipator. if the new t/stat is not digital the heat anticpator on the T/stat needs to be adjusted. slide the small adjuster arm under the cover to about .6 or .7 and see if the solves the problem. if the t/stat is digital it should be preset from the factory.
3. last resort have a service man check your pressure swith. could be a slow inducer motor, blocked or bad vacum line, or a restricted drain or flue pipe.
Good luck!

SOURCE: weatherking furnace is starting and stopping

This just sounds like a couple of problems. First, your blower is designed to only turn on once the heat exchanger heats up, so the flame will be on for a minute or two before the blower starts. it sounds like your blower is cooling down the heat exchanger too fast and causing it to shut off so it can warm up again...check blower speed for heat, it should be the lowest speed (black wire). Blue=medium speed, red= high speed. second problem could be your flame sensor rod is calcified, you just need to locate this and clean it off with some fine sand paper.it is located in the flames near the burners. Also change your filters, for proper air flow through your heat exchanger.

SOURCE: My Gibson Furnace clicks on but no heat comes out.

After four years I do not thing you have an effective warranty even if the company still in business. you need to open it first and clean it from any builod up dust and check the switch to see if it is working (thermostate)

I wish I was a furnace expert but I will give a push in the right direction. When a gas/electric fan runs it has two speeds. When you turn on the FAN ON switch it should run at the slower speed. If it doesn't turn on or turn off again when you turn it back you have a wiring problem or a thermostat problem. Make sure the thermostat is compatible with your unit and wired properly (on both ends). The other time the fan runs is "in session" when heat or cooling is applied to the system. It should run until the system finishes the cycle then a bit more (30 seconds or 1 minute) to blow the treated air completely through the ducts. If it doesn't stop then you may have a bad fan time delay or relay. Check parts for your model and various appliance repair site online.

Sounds to me like it is going off on a weak high limit switch. With the fan on it will prolong the event but will not stop it. I would check all of the high limit switches. It would most likely be one close to the heat exchanger.

Heat and Air run at the same time in my rv


yes, replace your stat but also make sure your wire going to y on the stat has not shorted with the wire going to the w on your t-stat. To check to make sure remove the t-stat and short the wire going to r to the y wire and the wire going to the g terminal if it has that. if cooling works with no heat it's more than likely in the stat, if heat comes on then you may have other wiring, circuit board issues

I have a dayton hanging furnace that after a few minutes the fan stops and burner keeps burning then a few minutes later the fan starts again and keeps repeating this cycle. model 3E845. thanks.


On the side of the heat exchanger is a fan Klixon that turns that motor on when the temp exceed 110f on the side of the heater. maybe that thang is going out or your fan motor needs oiling and is cutting out on overload. Next to the fan klixon is usually a limit. Both look the same. The fan klixon will have a marking stamped into the metal such as F-120 the limit will have L-240.

Induction fan motor cycles on and off , with no call for heat


Problem: Your furnace will not ignite the gas to produce heat for your home. When a furnace has a bad ignitor what I see most of the time is the following sequence of operation:


1. Thermostat calls for heat. 2. Draft inducer motor starts. 3. Pressure switch attached by a small plastic or rubber tube senses the negative pressure produced by the draft inducer and closes. 4. Draft inducer runs for 30 seconds to a minute before you hear a gas hissing sound. The ignitor did not glow, the flame sensor (a small metal probe about 1/8" in diameter, with a white porcelain base) does not sense the flame, so after 8 to 10 seconds the hissing sounds stops with no ignition of gas to heat your home. Your furnace shuts down and goes into a lock out condition until you turn your power switch back off and on again. Then the sequence starts all over again with no ignition of the gas. Solution: You probably need to purchase and install a new ignitor. I would suggest that you inspect your ignitor closely for cracks. Make sure you do not touch the ignitor with your bare hands. If you do not visually see a crack, then you could have a furnace control board problem or a limit, rollout switch problem. The furnace's control board might not be supplying the voltage to the ignitor. If your furnace lights and the gas stays on for 8 to 10 seconds, then shuts right back off, then you need to clean your flame sensor with light sand paper or steel wool. You might need a new flame sensor, but most of the time they can be cleaned an will work well after cleaning.

My Miller furnace occasionally stops in mid


If the flame looks good prior to the room air blower starting but becomes unstable when the blower starts, you have a crack or hole in the heat exchanger. I strongly suggest your technician do a test on it to see.

Furnace runs OK, but blower runs again a few seconds later


Could be a defective thermostat in the plenum.
When a gas furnace shuts down the fan(blower) will run until the plenum cools to the safe range. Usually 1 and 1/2 minutes.
Intermittent operation is a defective thermostat or relay.
