Question about Heating & Cooling
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.

I had the same problem with a Coleman. The problem is the blower relay. You can find this at http://mobilehomerepair.com

You have a flame sensor that may just need cleaning take out and take fine sand paper or emery cloth and clean

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.

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.

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)

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.
