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.

Identify gas control valve, with instructions for lighting each type... these instructions also show on side of water heater.

Knob rotated to off...means pilot light is off, and water heater is off.
Read instructions shown with each gas control valve shown on link above.
Don't forget that gas supply to water heater has to be ON. Gas shut off valve must be parallel with gas line.

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.

Hello
Sounds like the thermocouple is going bad.The thermocouple is a thin tube that runs from the pilot lite to the gas valve.
What it does is it sences the heat from the pilot lite and keeps the gas valve open to allow the pilot to stay on.
This can be easily repaird by shutting off power and gas to your heater and removeing the thermocouple from the gas valve,then unclip or unscrew it from the pilot lite area.
Any plumbing supply store or home depot or lowes should have these.

Once you get a new one,install to gas valve and pilot lite area then turn on power and gas to heater and follow pilot lighting procedure,you may need to hold gas on for 60 seconds.

Here is a picture of the thermocouple so you know what to look for.

We have an older (22 years?) 'Insta-Flame (model HE30 TN) natural gas fireplace insert. The pilot light is out, as we painted to inside of the firebox. The instructions show to 1) turn the dial to 'off'',...


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

I have an older monterey wall heater that is gas that wont seem to light. I cant even get the gas to start from the pilot can you help me?


You could have a plugged pilot line. You will need to get to the gas valve and shut the gas supply off. Once you did that, unscrew the pilot line that supplies gas to the pilot assembly. You can then turn on the gas supply and rotate the pilot knob to the pilot setting. Depress the knob into the gas valve. You should be able to smell and hear the gas come out of the hole where you unscrewed the pilot line. Don't do this with a cigarette in your face. Once you verify you have gas, release the knob and shut off the gas supply. Take a can of air and blow thru the pilot tube, first from the pilot assembly in the heater then from the open end of the pipe. Replace the pilot tube making sure you don't cross thread the fitting. Tighten well. Again turn on the gas supply, spray or rub some soapy water on the fitting you tightened, depress the knob and hold it. The soap will bubble up if there is a leak. Fix it. Now light the pilot.

Pilot light on . . . heat won't turn on.


Have you rotated the gas valve from pilot to ON position? You light in pilot but you have to rotate to position usually marked ON. Then the valve opens as long as the valve is getting a 24 vac signal to open. Cycling the thermostat will make a distinctive click in the valve.

My boiler will not fire up the pilot light is on, the thermostat clicks when asking for heat but boiler will not go on. What could be the problem ?


Best case, the gas selector switch is set to the pilot position. Rotate it to the full open position to allow the boiler to fire. If it is already in the normal operating position, you will probably need to replace the gas valve.

Drum rotates but does not give off heat


If the pilot will not light then there is an obstruction between the gas line and the pilot. Most times there is a particle that sticks in the pilot. The pilot needs to be disassembled to clear the blockage.

Usually the the pilot is a simple construction and one of the parts has a tiny hole that easily gets clogged. Obviously this needs cleaned.

If the problem persists, the must be a problem further up. check any elements in between. You could try to blow air through the system with various parts disconnected to identify the obstruction.

Dryer smells of natural gas


Of course, this applies to gas dryers only. If you smell natural gas near your gas dryer, do not light matches or a lighter and don't operate electrical switches or anything that might spark, igniting an explosion. Immediately shut off the gas valve that serves the dryer. If the smell is mild, ventilate the area, wait until the air is clear, and re-light your pilot light. If the smell is strong, move everyone outside, leaving the doors open to ventilate the house. Turn off the gas supply valve --located by the gas meter on the gas inlet pipe-- by rotating the valve one quarter turn with an adjustable wrench. The valve's oblong stem should be perpendicular (at a right angle) to the inlet pipe to stop the flow of gas. Call your gas supplier (or the fire department) from a neighbor's phone or a cellular phone outside the house.
