Fahrenheat Electric Convector Baseboard Heater, 240 Volt - Page 6 Questions & Answers
Low heat output
Hi,
first of all, have the thermostacts been checked,if not they will need to be checked,mainly dust can get into them.
if they have heating elements,ckeck to see if they are all in tact and have no dust on them.if this does not work then you will need new heating elements,which you might not get any more,if this is the case then im sorry to say that new heaters will be needed. i hope this helps and good luck.
I have a model UP2422B wall heater that glows very red when it first comes on and before the fan can kick in and cool it down. Is there a replacement heater available of the same size?
These heater elements should never glow red. The fan should come on at the same time the heater elements get power to heat up. If they turn red, the fan isn't starting fast enough, or is just turning too slow. Think of it like a toaster. They glow red but if you blow on them, they cool down until they aren't red anymore but they are still hot. I have this same heater. In the fan end opposite the fan motor, there is a little brass bushing (bearing) on the fan shaft that's mounted inside a rubber mount. Pop the rubber mount out of the heater housing, clean it up with degreaser and put grease or a heavy duty oil on the shaft and reassemble. If it still turns slow after that, it needs a new fan motor. You can probably match it up with the same motor from McMaster Carr or Grainger for cheaper than from Marley. I hope this helps

You may have to put a few drops of machine oil on the motor shaft. There is a felt washer on both ends of the motor shaft that absorbs and stores the lubricant. It probably is dry.

This thermostat is a DPST (Double Pole Single Throw) type meaning it will switch BOTH pairs of wires either ON or OFF. It is a type used primarily for 220 - 240 volt circuits and can switch up to 22 amps of load current. Most heaters will provide a wattage rating and some also provide a current rating as well. Since most electric heat circuits are connected to a 2 pole 15 or 20 amp circuit breaker (or fuses) via #12 copper wires it should work well. If connected to a circuit greater than 20 amps - as long as the heaters connected to the circuit do not draw more than 22 amps will also work fine.
If all is well so far, the continue. The thermostat should have 4 wires. Two of one color, two of another (black and red are common colors). One color group will be the LINE (powered) side, and the other group is the LOAD (heater) side. You should verify WHICH color group is which for best results. The switch will open and close a connection between the LINE wires and the LOAD wires.
The thermostat should be installed in an electrical switch box located on an interior wall at about 5 feet high and not above any heater or heat source. Do not locate it behind a door that swings open, etc. The box should be supplied by a circuit from the electrical panel that will connect to the LINE side color group wires *and* a circuit that will extend from the thermostat's LOAD color group wires to the heater's wire connections / terminals.
If running common #12/2 (for a 20 amp circuit breaker) or #14/2 (for a 15 amp circuit breaker) romex cable from the panel will have the Black and White wires connected to the thermostat's LINE wires and the Black and White wires in the #12/2 or #14/2 romex cable from the heater will be connected to the thermostat's LOAD wires. The ground wires will connect to each other AND a short length of the same size wire should be run from this same point to each: the ground terminal screw of the thermostat and (if using a metal electrical box) to the electrical switch box with a separately purchased green ground screw designed specifically for this purpose. Plastic boxes are not grounded.
