Troubleshooting a Rheem furnace that will not light consists of checking the spill switch, the HSI heater and the ignition control. Checking these items requires an ohmmeter, a voltmeter and a screwdriver. Completion of the project takes approximately a day.Know More
In the case of the Rheem furnace, hot air is released through a vent on the top of the appliance. However, if this vent is blocked, it can cause a backup of dangerous gases, specifically carbon dioxide, within the vent hood of the furnace. Inside the hood is a sensor called a spill switch. If the spill switch has detected the build up of hot gas in the hood, it will open, allowing electricity to run through the switch and turn off the furnace. This switch needs to be manually reset in order for the furnace to operate.
The HSI heater is the component of the Rheem furnace that ignites the gas. It's also commonly referred to as a "hot stick." This hot stick is very fragile and has a tendency to break if used frequently. Checking the HSI heater is relatively easy and simply requires taking the two probes of the ohmmeter and holding them against the hot stick. If they register that electricity is flowing through the component, then the HSI heater is broken and needs to be replaced.
Checking the ignition control requires turning the furnace or thermostat off and on. This may reset the ignition control pane, in which case no further troubleshooting is required. If this does not reset the ignition control panel, then while the power is on to the furnace, touch the probes of the voltmeter within the space designated by a "TH" and "GND" on the ignition control panel. If 24 volts are registered, then the ignition control panel is broken. If no electricity registers, then the problem with the furnace is not with the control panel.
The date of manufacture of a Rheem furnace is encoded in the product serial number and is simple to decode using charts available on the Rheem website or other online resources. Some models have a separate date stamp in addition to the coded serial number.Full Answer >
It is safe to burn diesel fuel in an oil furnace. Oil fuel is very similar to diesel fuel and the biggest difference is the color of the fuel. Diesel fuel also comes in more grades than oil fuel.Full Answer >
The methods of replacing gas control valves on water heater varies depending on the design of the water heater. However, the task of replacing the gas control valves will usually require tools, such as a pipe wrench, screwdriver, a pair of pliers and a few lengths of pipe tape. It will also be a good idea to wear protective overalls and working gloves while replacing the water heater component.Full Answer >
To relight a water heater's pilot light, switch the gas valve on the heater to pilot, and then apply a flame to the lowered gas flow. Next, turn the heater on.Full Answer >
