Pool heater comes on and gas enters unit for about 5 seconds and then the gas shuts off. natural gas

This could be the flame sensor. If you can look into the firing chamber there should be a steel rod about 5" long that dangles into the gas fire jets. Turn off the unit. If you take the fire sensor out and gently rub it with steel wool and replace it, it may start working again. If it does, great, but order a new fire sensor and replace the old one when it comes in. They are very cheap.

Sta-Rite Propane heater ignites flame and within 2 seconds shuts down.

With the limited information provided above, I would say that it is your flame rectifier (flame sensor).
If the heater ignites, and the flame sensor is bad, it will go out right away as a safety precaution.

Below is the parts/troubleshooting manual for this heater. You can find the part number for your flame sensor, and replace it.

Your igniter is working fine. The problem is the flame sensor needs to be replaced. The flame sensor is a safety feature. If it doesn't detect heat from the igniter it prevents the gas from flowing. A new flame sensor will cost about 30 - 35 dollars. You can buy on online here

Kenmore gas dryer #110.97282100 won't heat. what part do i need?

Your easiest (cheapest) starting point is with the thermistor (flame sensor).
You can easily check that it is in direct contact with the pilot... and at the same time - check the ignitor is sparking

1. Check for ignition - if not igniting - replace ignitor.
2. Check/clean Flame sensor - if pilot is lit - replace the sensor.
3. If voltage at the gas valve checks out (from flame sensor) - gas valve should be replaced.

Goodman Dependable 92, ignitor and fan comes on for 3 seconds, furnance does not turn on. Goes through 3-4 cycles, then shuts down furnance. If it is the flame sensor, where can one buy parts?

Do the burners come on? If so then yes it probably is the flame sensor if not then there is another issue not the flame sensor. The flame sensor could just be dirty take the flame sensor out and clean it with a piece of emery cloth or lite sand paper and put it back in and this should get the burners to stay on.

I have a Whirpool gas range. Everytimme I hit bake and start the oven starts to heat up. After about 20 seconds it shuts off. I got error code E303 so I replaced the oven temp sensor but that didnt fix the...

The flame sensor is bad. Go to repair clinic. com and put in the model and it will pullup the parts for your oven. Buy the flame sensor. It has to 'see' the gas flame to remain open from the gas valve.

The pilot light will not stay light

The flame sensor is not sensing flame. If it is a thermocouple sensor, they can be purchased for 6 bucks and replaced in 15 min.

Some units have a different type of flame sensor and are a part of the ignitor assembly. In that case, the ignitor assembly would have to be replaced. Those usually run 20 to 60 bucks.

There is a remote possibility that the sensor and pilot flame shroud need to be cleaned, due to rust and other corrosion preventing the flame from properly contacting the sensor. You can try cleaning that first, but chances are you will simply have to replace the sensor.
