RLP 30 portable heater

I'm not sure whether this is a gas unit or not. With many gas heaters, the blower comes on when the heat exchanger gets hot enough and goes off once the heat exchanger cools. Other things are happening before the blower goes on. The blower is normally controlled by a "fan control thermostat". This stat actuates the blower when the furnace is hot enough so that cold air is not being blown around and allows the blower to run until the furnace cools enough to get out the remaining heat after the flame shuts off but not so long to again allow cool air to blow around. If this fan control is malfunctioning, you will get erratic runs from the blower or the blower may not run at all or run long or continuously. The fan control is the first thing to check.

No you can not convert this unit to natural gas. They do not make a conversion kit or give us any sizes to drill out any orifices.

Does the fan come on when you turn the Fan to ON at the thermostate? If it does then it could be the blower board not turning the low speed blower tap on. Or the Fan & Limit switch not working. If the fan doesn't come on in the on position then the blower motor could be out or the run capacitor.
If the blower comes on it the ON position then you can run the heat with the fan in the ON position till you can get the heat relay looked at.

I would guess that the fan off setting on your limit is set a little to high. If you have the manual you can see what it says about changing the running time for the fan after the burner has shut off look on the control board and you should see two switches,one to set the time for burners to fire before main blower starts and one to set time for fan to run after burners shut off. To help with the problem you are describing set fan run time up so fan wii run longer. Hope this helps. Thaks.

Hi, sounds like the problem would be more likely in your furnace than with your thermostat. I would suspect a defective fan switch, these switches are temperature activated and turn on the blower at a lower speed than the Fan "on" would.

then you need toi have them check the fan high limit that is mounted in the blower compartment. if it's closed then the blower fan and the conmbustion air fan will run together.

Chk and make sure the thermocoupler bulb is in the pilot flame, If it is, it is defective and needs to be replaced. Easy, inexpensive repair. Good Luck, Ned

Sounds like a bad thermocouple.

Reddy suggests: 1. Propane supply may be inadequate 2. High surrounding air temperature causing thermal limit device to shut down heater 3. Restricted air flow 4. Damaged fan 5. Excessive dust or debris in surrounding area solutions are: 1. A) Refill tank B) Provide additional and/or larger tanks. 2. This can happen when running heater in temperatures above 85° F (29° C). Run heater in cooler temperatures 3. Check heater inlet and outlet. Remove any obstructions 4. Replace fan. 5. Clean heater. could not get manual for your exact model but if you want manual for RLP 125 then; http://12.153.20.74/manuals/113893-01C.PDF appears to be the same beast. Hope helps :)
