Roll Out Sw Open (2024)

FAQs

Why is my propane heater sparking but not lighting? ›

One of the most common reasons for a furnace not igniting is a faulty thermostat. Ensure that the thermostat is set to a temperature higher than the current room temperature. If it's battery-powered, replace the batteries. If your thermostat is programmable, verify that the programmed settings are correct.

A Buildup of Soot and Gases

A high concentration of gases within the chamber will cause the flames to grow bigger each time you turn the furnace on. Flame rollout is extremely dangerous because it involves burning toxic gases like carbon monoxide instead of clean natural gas.

This is generally a heat activated switch down by the burners. If the vent gets plugged, the heat exchanger...even high winds...can force the flame/heat backwards and trip this switch. Some are able to be reset others need to be replaced.

The model is inside the pool heater. I do not need the Aqualink model number. Anyways the answer is as I mentioned before. (open water temp sensor) That means the control board can no longer read the temperature of the incoming water.

A bypass valve is put in place near the intake to stop water from flowing through the heater when it's not in use.

In order to tell if the valve is open or closed, the general rule is, if the handle is switched 90deg to the flow, it is off. As you can see from the diagram above, if the handle is in line with the flow path, it is on. Simple.

Check the Power: If your Raypak pool heater isn't working at all, the problem could be something as simple as a lack of power. Go make sure there aren't any tripped circuit breakers in the fuse box, then check that the unit's time clock is set to the “On” position.

One of these safety features is the flame rollout sensor or switch. The flame rollout switch ensures that the flame doesn't “roll out” from the combustion chamber in search of oxygen. Hence, it protects your home from the dangerous effects of a furnace fire.

The best way to verify that you need a new thermocouple is to see if your pilot light is lit. If the pilot light can't hold ignition, that means either a problem with the gas supply or, more likely, the need for thermocouple replacement.

Defective Igniter or Pilot Light

If it makes a clicking noise but your furnace won't ignite after its combustion cycle, then it's more than likely going to need to replace the electronic ignition systems.

Why won't my propane water heater ignite? ›

In many cases, the reason that you can't get your pilot light to ignite is that the pilot tube is clogged. This is a small metal tube that supplies the gas needed to ignite the pilot and keep it lit. The pilot tube often becomes clogged with debris, and this will prevent gas from flowing to the pilot light.

The flame rollout switch is normally closed and opens on high temperature from the flame. The switch is meant to open if the flame is pushed backward away from the heat exchanger area where the flame should be traveling toward.

Your furnace has a safety device that is designed to detect flame. rollouts. It's called a flame rollout switch, and it cuts off the. gas supply to your furnace when it detects higher temperatures than normal. immediately outside the combustion chamber.
