Tip & How-To about Heating & Cooling

Yearly maintenance on Reddy Heaters

If your unit is more than a couple of years old you probably need to change the filter in the back and set the pump pressure. A good indication that you need to do this is if your unit turns on, starts to heat, and almost immediately stops and blows smoke out of the end. The air/fuel mixture is not correct, probably due to a partially clogged filter. These heaters use the air pressure to determine the amount of fuel to pump. Obviously if the pressure is not correct, too little or too much fuel will be pumped. Either situation causes the unit to shut down and smoke.

Both the filters and the gauges to set the pressure can be found at www.reddyparts.com along with a good explanation as to why you need the gauges. If you want your unit to run properly, and efficiently, I recommend purchasing the gauges. They make setting the units easy as well as possible.

The pressure is set by bleed air pressure and must be exactly 3.5 psig. The gauge is the only accurate way to do it. The filters clog and change the pressure. When the difference is enough the unit will not run.

Now with that said there are several other things which you should check yearly. Check the fuel tank for water. Remove any you find by draining the unit. Remove the cover on the right side, as you look at the unit from the front, and remove the circuit board. Check for cracked connections. These things vibrate alot. If you find any broken solder connections resolder them and reattach the board. Until I completely resoldered my board I kept having problems.

That should take care of the unit and get you back to making heat.

i have a swimpro sand filter it is 5 yrs old and this season when i started it up it doesn't seem to have very good pressure i have backwashed it three times and it wont even run my pool cleaner no pressure i just changed the sand last year any ideals ?


If there is not much pressure, the problem is with the circulation system. Probably the pump.
When a sand bed gets old the pressure goes up on the guage, but the filter doesnt do much. When there is a lack of pressure, its due to a problem with the water flow. Usually a clogged impeller, strainer basket, or skimmer basket.

The most common solution for a loss of pressure is to dissasemble the wet end of the pump, clean out the impeller, and replace all o-rings and seals, including the shaft seal. This will revitalize the performance of your pump.

1998 chevy 1500 pick up. good fuel pump, new fuel filter,fuel relay good. starts good, dies instantly. what to check next.


If your fuel system is all correct and working it needs to be an ignition problem-and the usual suspect is the crank sensor, which coincidently does not set a CEL-so, since it is very inexpensive (usually less than $50) and not difficult to change int a 350, take a chance there-you could try to remove the connector and clean off the connection first-worth a shot.

motor "bogs down" at roughly 120 psi...almost stops


You suspect this unit as being a two stage because of the unusually high cut off pressure. It is a single stage and the motor really has a difficult task and is being pushed to the limits. to reach this pressure. We usually reset the pressure to lower setting ~~ say around 140. Your pump probably has a leaking intank check valve (brass fitting at tank) or leaking valve plate in pump. Simple tests : with pressure in tank unplug compressor from outlet and listens for air leak around pressure switch. As you unplug the running compressor from outlet you should hear air leaking from pressure switch for just a moment as air is let out of airline from pump to tank. If air leaks out till zero pressure then change the valve. If tank holds pressure then valve probably ok. Next test, with no air in tank and air filter removed, plug in compressor and feel intake port for strong suction. If the valve plate is bad, suction will decrease as pressure neers the 120 mark till the point of feeling that air is actually blowing out of intake. With good valve plate there will be strong suction untill unit reaches set pressure. If valve plate is bad also change the cylinder and piston ring. Good luck with your repair.

fujitsu heatpump 13 years old is not heating room as it used to.filters are clean.i have gauges and would like to know what pressures are good and what pressures indicate low refrigerant or worn compressor.unit is about a 7kw heating model.


The refrigerant and compressor are related in cooling the room.As for heating problem the thermostat needs to be checked.
if you're used to a certain temperature of air and your heat pump is producing much cooler air, take the following steps. (Note that a heat pump may go into a defrost mode to prevent icing. When this happens, it can temporarily output cold air. Also be aware that the heat pump will have to work harder to produce heat.)

1) First be sure the thermostat is set properly. Try raising the set temperature 5 degrees F. and waiting a few minutes.

2) Be sure the room-heating registers are open.

3) Check the heat pump filter. If it's dirty, change it.

4) Be sure the auxiliary heating elements are working . 

5) Clean the coils of the outdoor condensing unit.
If still the same problem then thermostat needs to be checked and replaced.
Thanks.

I have a Reddy Pro 115 BTU kerosene heater the fan starts but shuts off after about 5 to 10 seconds


When you say that the fan starts then stops I assume you also mean that the burner starts and stops. If this is correct and the unit is more than a couple of years old you probably need to change the filter in the back and set the pump pressure. Both the filters and the gauges to set the pressure can be found at www.reddyheat.com along with a good explanation as to why you need the gauges. The pressure is set by bleed air pressure and must be exactly 3.5 psig. The gauge is the only accurate way to do it. The filters clog and change the pressure.

Remove the cover on the right side as you look at the unit from the front and remove the circuit board. Check for cracked connections. If you find any resolder them and reattach the board. That should take care of the unit and get you back to making heat. Let me know if you need anything else.
