When a heater runs for 30 seconds or les some heaters run or about 1 minute this is mostly a problem with how much water is getting in the heater if is too little the pressure switch cuts the heater off or the high limit switch is shutting off the boiler why because the small amount of water getting inside your heater get hot to fast and make the heather to get so hot and the high limit switch turns the heater off the solution is to check your filter make sure is clean or cleaned they get dirty soon if your filter is clean and still doing it check the bypass in the heater normally is located next to the lines going in and out in the heather lines I have fix so many heaters my self I use to have a business in california as swimming pools repair so I know this and your heater is not to big to say is your gas regulator gs regulator is a common problem on heaters ranging on size from 30-36-40 BTU

My 1989 f350 duelly starts in am and dies quickly bought coil and ecm cap rotor and backfires and shakes and dies any ideas.i was thinking distributor or fuel pump please help


If you spray starting fluid in the air intake, does it stay running? I would go to harber freight and get a cheap fuel pressure tester and hook it into the fuel line. It hsould be about 40 psi, and hold for about 30 minutes after shut down without bleeding down too much, like 5 psi.

Try this too. Turn key to ON, wait 5 seconds for the pump to shut off. Then turn key off and listen for the realy to "Cclick" under the dash (about 10 seconds). Repeat this. Then start engine. This primes the lines & injectors if you are getting bleed down due to a bad check valve in the fuel pump.
report resuts. pleasre rate assistance.

Heater turns on and heats garage to set temperature, than shuts off. when the temperature drops, the unit kicks on again. everything starts working again but only for a few seconds and than shuts off. it...


Problem: Your furnace will not ignite the gas to produce heat for your home. When a furnace has a bad ignitor what I see most of the time is the following sequence of operation:


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.
