SOURCE: Turntable does not rotate when switched 'on'.

K, I'm not familiar with that particular stereo unit but there were a lot of stereos from years gone past that used a turntable made by BSR. When you activate the switch to start the turntable listen closely to the record platter for a hum or possibly the sound of a motor turning (they're quite quiet). Is the switch lever you pull rectangular made of black plastic, you pull it towards you one click to start the record and pull it one step further (spring loaded) to make the tone arm lift from the record automatically? Just want to make sure I'm talking about the right turntable before we continue.

SOURCE: My fan limit switch will

Make sure nothing is bent and causing added pressure to keep it sticking.

You will likely need to replace the limit switch.

I don't know your model, but its probably 2 wires, 2 or 4 screws and runs about 20 to 40 bucks for the part.
Turn the power off first.

SOURCE: I can't turn the bar pressure up on my Vaillant VCW 221 Boiler

on the pipework below there may be a silver braided hose with one or two valves on the end. turn the valve(s) so the handle is inline with the pipe this will allow water from the mains supply into the heating circuit , remember to keep an eye on the pressure gauge. fill the system to 1bar cold then shut down the valve(s). turn on the boiler and it should be ok, if you lose pressure again then you may have a leak somewhere which needs to be found.

SOURCE: WE can get the pilot light lit but it will not stay on

You will need to check the pressure regulator for the gas.
It sounds like the gas pressure is to low to keep the pilot lit.

Working on a gas appliance is not recommended unless you are an experienced technician. There is a multitude of things which can go wrong and seriously endanger residents if a repair is not done correctly. That said, the draft inducer motor should start the cycle off. If the pressure sensor shows it working properly, then voltage is sent to the ignitor and gas valve (for pilot lighting). The flame sensor then tests for a pilot, if present allows voltage to the main gas supply, if not puts the system into a timeout and allows it to retry after a set time (2-10 minutes usually). If all of these parts are working properly you may still have an issue with the door switch, the gas controller, the gas supply, etc. which can simulate your issue. Try following that path of logic after eliminating the door switch and fuel supply as the culprit. If you locate the problem you still may have trouble obtaining the proper replacement part as most supply houses do not sell to the general public.

On some gas valves the pilot setting is on the same dial as pilot on and on .on others the pilot light has aseperate button on right side of control dial. If yours has this there will be a cut out on cotrol dial that must be aligned with button to allow it to be depressed to light pilot. If yours has this align control dial cutout with pilot button,depress button and light pilot,hold for about one min. and slowly release,if pilot light stays lit,turn down thermostat and rotate control dial normally to right . There should be arrows or marks on dial and gas valve to line up. If pilot light stays lit turn dial to next position and check to see that pilot is still lit. This should be on position, turn up thermostat and burner should light. If your dial has pilot light setting on it then rotate dial to each position,try to depress dial and when you have right one dial will depress allowing you to light pilot. Follow same procedure as above and you should be in business. Hope this helps.Thank you

The gas pressure is not stable. Either gas pressure valve is problematic, or the burner orifice is dirty and the pressure out is blocked. You can try to clean the burner orifice first.

Pilot LIGHT KEEPS GOING OUT OUT


The pilot light jet may have got a little bit of dirt or grit in it which is preventing it from keeping alight. If the pilot light has only a weak flame, the whoosh of the main burner igniting can quite often blow out the pilot. Try probing the jet with a fine piece of wire to see it the blockage can be dislodged. You may have to unscrew the jet to clear it by blowing air through it. Make sure gas is turned off first before removing any parts.

The pilot light also has a thermocouple that allows gas to the pilot light while the flame is burning. If pilot flame goes out for any reason, it shuts the gas off to the pilot jet to prevent unburned gas collecting and causing a safety hazard. The thermocouple is bypassed by a switch during the initial ignition and once the thermocouple warms up after a minute or two of holding in the bypass switch, it should maintain the pilot. If, after cleaning, the pilot light keeps going out, it would seem that your thermocouple is faulty and needs to be replaced.

We have an intertherm heating system, its probably 30 or more years old, and we cant see a pilot light, and we havn't been able to light it. the model is mac 1175.

I have an Amana dinosaur model P67470 dual HVAC. It's blowing fine but the pilot light's goine out. I can find the valve but don't know where to light it?


Not an easy one to get to. From the gas valve, follow the small 1/8" diameter (usually copper) line toward the heat exchanger. It will lead to a pilot assembly just over one of the burners. Using a long match or shis-ka-bob stick, hold a flame just over the pilot assembly until you see the pilot light. Remember you will need to have the gas valve knob on the Pilot setting and depressed into the gas valve. Continue to hold down on the knob for 15-30 seconds. Then after the pilot remains on, rotate the gas knob to the On position. Hope this helps!

Need to know how light pilot


First step turn the thermostat off. It is very important.
Next find the knob on top of the gas valve you will see writing on it turn it to pilot it could be in the off position so move it to pilot depress the knob where it goes down about one inch. Take a long lighter long match or something like that and hold at the pilot it will be back in the furnace by the front of the burners. Once the pilot lights hold the button for another 30 seconds. Release the knob now the pilot should be on and the next step is why you turned off the thermostat rotate the knob to on position. Go to the t-stat and turn on the heat.

I need to know how to light the pilot on my somewhat old water heater. The model is called the challenger 5 the model number 153.331471


On these older gas water heaters there is a gas control with temperature selection and below that is a removable cover. Once you remove the cover you can gain access to the pilot. You must rotate the knob on the top of the control to the pilot position. When in the pilot position, hold the red button down and light the pilot. Continue to hold the button down after the pilot is lit for about one minute. If when you release the red button the pilot goes out, try one more time. If it goes out again after releasing the button your thermocouple is bad and must be replaced. The thermocouple generates a millivolt electrical current that hold the gas valve in the operating condition when the pilot is lit. When the pilot goes out there is no heat to generate this small electrical field.
