Hi there,

I am not familiar with that particular heater but sounds like blocked jets. You need to blow out the jets with compressed air. Easiest way is to remove the hose at the fitting and blow compressed air through the gas connector where the hose fits on. Make sure the buttons or switches are in the on position. Also if you can see the pilot light (where it lights up with gas) blow down that hole as well. You might see some dirt or what appears to be dirt come up and out. Try that and if it works think of it as a bonus. If you have the same trouble you will need to remove the cowling to get to the actual jets themselves. If it has candle make sure you blow the candles as well as they tend to carbon up - you will probably see a whitish dust come out - keep blowing them till you don't see any more dust. Be careful not to use excess pressure on the candles as they are brittle and can break. Hope this helps.

I have a 2000 sable been in the family since New I start it with starting fluid it runs until parked then won’t start again then repeat process what do you think is wrong

Next time you try to start it, turn the key to RUN (not start)for 2-secs. Then turn to OFF. Repeat 3 times. Then try starting. If it fires right up, that's a sign of a leaking check valve in the fuel pump. Turning the key to RUN 3 times triggers the fuel pump to go into "prime" mode to rebuild fuel rail pressure. When fuel pressure is back up to spec, it fires right up.

Water spits in tank but all inlets are open

It may be time to descale. Most models will give you a message when it's time to have the mineral deposits cleaned.
Empty water resevoir. Disable auto off. Pour approx 48 oz of undiluted white vinegar into resevoir. PLace large mug on drip plate, run brew cycle, dump contents of mug in sink. DO NOT USE A K-CUP.
Repeat this process until the add water light is indicated.
Let brewer stand for at least 4 hours while still on.
Discard any residual vinegar in the resevoir and rinse thorughly.
AFTER approx 4 hours...fill resevoir with water.
PLace a large mug on the drip plate and water brew cycle. Pour the contents of the mug into the sink.
REPEAT this brew process until the add water light is indicated.
YOU MAY NEED TO REPEAT THIS "RINSE" PROCESS if you notice any residual taste.

I ran my 2006 chevy uplander out of gas now it wont start even using starter fluid

after putting some gas in your tank, step on the gas pedal repeatedly (step to it fully), then while pressing, start your car. the fuel was completely drained from your system thus there are no fuel to burn in able for your car to start.

pressing the gas pedal repeatedly (around 10 times will do) will put some fuel in your combustion chamber, so the car will now have something to burn if you will start the car

Ran fine last night drove round trip prob 75 miles no prob parked tried to start in morming keepd cranking wont start less than 1/4 tqnk off gas banged on gas tank while cranking still wont start any...

One way to check the fuel pump is to turn the ignition to on and listen for the pump to run. It should run for a few seconds. It may be a couple of seconds after you turn the ignition to on before it runs. Normally you can do this repeated times.

If you don't hear the pump run that is most probably the problem.

How to get front brake pressure after changing master cylinder, bleeding didnt help or maybe im not doing it right

vacuum bleeding is best for these brakes. To do it without a vacuum pump you must pull the handle very slowly and pause about three seconds between handle pulls to allow fluid to refill the piston chamber.

Why does the Oven take so long to light?

It sounds like it might be a sticking gas control valve for the oven or the hot surface igniter for the oven might be weak. You will need to turn the oven on and off completely several times until the problem happens. When I say completely I mean turn on the oven control and watch the igniter start to glow. Then when the oven burner comes on(should within a minute) shut of the oven control and wait for the igniter to stop glowing completely and burner to shut off completely. Then repeat the process again. If you try it about 10 times and nothing happens then the problem will be difiicult to identify. If you turn on the oven control and the igniter comes on but the gas burner does not then try giving the gas control valve(located in brolier/storage compartment) a tap with a wrench. If the burner suddenly comes on then the control valve was sticking. Try repeating the shut down/turn on process again. If it does not do it again you may have fixed the problem...if it does you will need to remove the igniter and test it with an ohm meter(should read at least 500 to 800 ohms). If the igniter is testing good and glowing brightly then the gas control valve would be the suspected problem. And remeber to be very careful when doing these testing procedures so you do not hurt yourself.

I have the book (list) that comes with the remote. It explains how to do a "code identification". It's pretty simple. Press and hold the Codesearch button until the light stays on ... then press and release the "Mode" button (the button that represents your TV or DVD or whichever device you are starting with, in your search for a code). It will blink briefly once and then stay lit. Now press and release the Codesearch button again (the indicator light will briefly blink). Now, to find the first digit of your code, start at "0" and enter slowly, one at a time, 0 thru 9 until the indicator light blinks off. THAT was the FIRST number of your code. Write it down. Now, repeat the process to find your second number of your code - starting over at "0" and enter slowly, one at a time, 0 thru 9 until the indicator light blinks off. THAT will be the second number of your code. Continue until you have all 4 numbers. Repeat for each device, until you have all codes desired.
