Cleaning the flame sensor has nothing to do with blower motor not turning on. You either one of the following problems 1 bad cap for motor. 2 bad motor. 3 bad limit on blower housing or 4 a bad board. You will need a volt meter to check for these problems. Try seeing if the fans runs with unit of and fan switch turned to on. Also does motor hummmm. Is motor cage free ( can check by manually turning) If motor doesnt humm and the cage is free wheeling then you will need to find out if you have power going to the motor. If you find out that you do then you will need to change blower motor. If you do not have power then you will need to check limit with continuity tester on volt meter. If that checks fine only 1 thing can be wrong and that is the board.

SOURCE: Gas Furnace is not heating anymore.

the fan you hear come on at a call for heat is most likely just the inducer motor. the click you hear is probably the relay for the hot surface ignitor which should glow red, then in turn ignite the main burners. your going to have to determine if the ignitor is coming on. if it isnt the ignitor is bad and will need to be replaced. if it comes on and than shuts off after a few seconds the ifc board is probably at fault

Short answer, yes. However you could have another problem. Replace the thermocouple that keeps the pilot lit. You can get a universal one at any good hardware or farm store. Make sure the new thermocouple is well into the pilot flame. If the blower knocks out the pilot flame again, I would be suspecting cross contamination from a crack in the heat exchanger. As the exchanger heats up, it may be causing a small crack to open and allows the blower to extinguish the flame. It may also be causing a leak of Carbon Monoxide into the heated room air. I would get it checked out very quickly.

SOURCE: my siemens rev 16 hydronic

Always look at the bottom of the screen at the 24 hr clock to see what time the thermostat is programmed to come on and off.You can then instantly see if your heater
should be on either T*& temp or TC temp. if the heating is not on when the time clock
indicates that it should check  to see that the time is set correctly.
Also check out the battery voltage.Is it  low or OK.

SOURCE: I have a few issues

Hi, look 9/10 problems are to do with either the thermistor or thermostat, Especially when the faults is intermittent, and sporadic.or perhaps the Main Controller. Always check the Gas flow & regulator diaphragm is OK..too..

The fact that it will start sort of "Proves" it somewhat it is just that it will not stay lit and is hard to start, now both of these can be related back to the thermostat &/or sensor being faulty.

All one can really do is check the Input sensors are working and check that the output devices, or signal to them are, working correctly too.

Always check the Flame sensor too, that's the blind end copper hose like thing that sits in the Flame, when it's Pilot light is lit.

Often it is sensor related, but if these prove to be OK, then the next thing to suspect is the Main Controller, which may contain the Thermostat too, but again replacement is the only option..

It sort works by when started the "Brain" checks all safety sensors and see if all are OK, if all are OK the gas valve will open, the Igniter will light the gas a Flame will be present in the Pilot light, and the Flame sensor that "Sees" a flame and continues to keep the gas going, it now checks the thermostat and if the desired temperature is under what is set, if it is then the gas flow ramps up, Burners go and the fan kicks in and hot air is distributed around. This continues until the Temperature sensors signal the thermostat that an equilibrium has been reached and the burners lessen or go Off until the temperature again drops to below the set threshold and the cycle starts again.

However this website below explains how to repair these type of furnace and should be a great help.

I have a kia amanti 2005 both heat up but i have no heat in the car. what can b the problem

"Both" what heat up? Both heated seats? If so, the heated seats are heated using electrical current. The cabin heat from the vents is heated from engine coolant. The car will need to be running several minutes before heat will start blowing from the vents. If once the engine temperature gauge gets up to normal you still are not getting heat from the vents and are certain you have the climate control settings correct to be requesting heat, you probably either have a blend door issue or an issue with the valve that allows coolant to circulate through the heater core. I'm assuming that your blower motor is working and you can feel air flow, just the air flow is not warm. If you are not getting air flow, then the blower speed controller may have failed, the blower motor may have failed, or some other issue is preventing power from getting to the blower motor.

There is no hot water coming from my truma heating system in my motorhome. The blown air heating is working

On Facebook there is a group called 'Hymer Owners' and they have over a thousand members many of whom past their knowledge on for others. If you Motorhome is not a Hymer, then try searching for the name of your Motorhome manufacturers group. Best info I've had for my MH.

hot air not being directed to vents? Check vaccuume hose under hood

1 Answer

I have a 1999 Damon Challenger Motorhome that blows cool air from heater .

Check the hoses to see if each hose is warm, usually 1 is warmer than the other, that enter the heater core from the engine.
If both are warm issue is inside vehicle, possible vacuum operated valve for venting or a cable, sometimes items drop down from dash, like toys, pencils, etc that could stop the action of the vents that adjust heat.
If 1 is cold then look for a valve possibly inside engine compartment on one of the heater hose runs, either vacuum line fell off, cable fell off or valve could be defective if no heat passes.
If no valve, then chances are the heater core itself is clogged and needs to be replaced.
This is all assuming that you have proper coolant level, the thermostat is functioning correctly, and your water pump is working, those should be verified as well when inspecting your heating issue.

Thermal fuse failure

If the relay sticks, that will cause overheating and the thermal fuse to blow.

No in car heating,blowers working fine but it wont produce heat. Its a 51 plate grand cherokee Thanks

If it won't produce heat then you have an issue with your heater core. The heater core could be bypassed, in which case no hot coolant will get to it to produce heat inside the cabin. The heater core could be stopped up with dirt/debris, in which case the heater core can't radiate heat to produce heat in the cabin. The ducting in the dash could not be allowing the hot air to flow to the vents - therefore no heat in the cabin. I'd start with the heater core and check to see if it is bypassed. This generally happens on older vehicles because the parts can be harder to find.

Inducer motor operates low RPM in low and hi fire modes. Microprocessor problem. Roll out temp. switch trips in both levels of heat operation. Will operate in ''Emergency run'' mode. ( Full Heat )

Sounds like you have a vent issue. The fact that it
does not matter what stage of heat you are in points
in that direction. Did you recently install any kind of external fan, wood fireplace or another gas appliance.
Any of these could cause what you are experiencing.
.Make sure the vent is not plugged. Disconnect vent at furnace and check that out

Dryer (electric) seems to heat up initially, then cool off and not get hot enough to dry clothes. What is wrong?

Check the following areas thoroughly to address this issue.

1. Venting
Make sure the dryer vent hose, as well as the rest of the vent duct, is not clogged.

Unless regular maintenance is performed, chances are there is a lot of lint accumulated inside the dryer. This might affect the drying time and could be a fire hazard. Make sure to have your dryer cleaned regularly. Because this might involve taking most of the dryer apart, it is recommended to have a qualified appliance repairman perform this task.

2. Thermostat
There are a couple of cycling thermostats inside the dryer. If one of them breaks down, it might affect the dryer's performance. Replace the defective thermostat.(usually located inside the unit on the actual blower housing or inside the vent duct)

3. Heating element
A heating element might only be partially burned out, in which case it would still work but will take longer time to dry the clothes. Replace the element if found defective.
