How to Change the Pressure Switch on Your Gas Furnace
Your gas furnace is not working and you think that the pressure switch is bad. Here are some things to check and the steps to replace it. Replacing is not very difficult at all, in fact it is one of the easiest thing that you can replace yourself.
Your gas furnace purge blower runs and never shuts off but your furnace is not producing any heat. Or your igniter will glow, light the burners and then the furnace will shut right back down and try to recycle all over again. Either one of these conditions are common if the switch is going bad or has failed.
You can check the switch by placing a jumper wire across the wires going to the switch once the purge blower has started. If the burner lights and stays lit the pressure switch is probably your problem. Could be a weak blower, but I would try the pressure switch first; it is much less expensive to replace.
Once you isolate that this switch is faulty, then you can change it. This is very simple. For most furnaces the wiring is low voltage, so the risk of shock is minimal. You should still turn off the power to be safe. Remove the screws that secure the switch and then just switch the two wires over to the new switch and secure the screws again.
That's all there is too it a very simple operation.
Turn the power back on to the furnace. Re-fire the furnace and check the operation of the unit. It takes a while for the unit to cycle through the lighting process but you should have a furnace that now heats your house just fine.

Compressed Air Hose Leaks and Air Hose Safety
Ask a Question:
What does OSHA say about hose safety?
Answer: An OSHA guideline publication states:
Hoses, cables, and other equipment shall be kept clear of passageways, ladders and stairs.
OSHA says reduce your slips, trips and falls. Slips, trips and falls constitute the majority of general industry accidents, which cause 15% of all accidental deaths, and are second only to motor vehicles as a cause of fatalities. The OSHA standard for walking and working surfaces apply to all permanent places of employment, except where only domestic, mining, or agricultural work is performed. Consider adding reels to increase safety & efficiency with your electrical cords, welding cables, air hose, oil, grease, liquid/water or fuel hoses.
Ask a Question:
Why should my plant use Air Hose Reels with our air tools?
Answer: If your business or plant has multiple air hoses running from your air compressor to a variety of air tools, then industrial air hose reels can be one of your most effective equipment additions you will ever make, as well as one of the safest!
Here are 5 Reasons to use Air Hose Reels:
1. Efficiency
Hose reels make all your hose handling more efficient. An organized, clean workplace is proven to be more efficient.
2. Safety
Hose reels decrease you chances of injuries from tripping hazards. Reduce accidents and insurance expense: Slips, trips and falls are the leading cause of work stoppage in industry.
3. Protects Equipment
Hoses (and cords) last five times longer when stored on a reel. This can save you from replacing hoses as often.
4. Stops Leakages
Hoses on reels can reduce the threat of expensive air leakages.
5. Increase Productivity
Locating your air hoses when and where you need them increases productivity. All these factors help improve your work environment, which saves you time, equipment and money.
Have you ever wondered what that hissing sound is when you walk through your plant or shop area? Most likely it is a COMPRESSED AIR LEAK. But what about the air leaks you can't hear? Size cannot be judged by sound.
Do You know how much your AIR LEAKS are costing you? A Department of Energy publications states:
Compressed air leaks can account for 20% to 30% of compressors cfm output in small to medium size plants.
In other words- you could be losing up to 30% of your compressed air because of AIR LEAKS! That is your money leaking away! It is worth the effort to find and fix your air leaks.
Ask a Question:
How do you estimate the SIZE and COST of an AIR LEAK?
Answer:
Here is how to estimate the size of air leaks:
It is not very hard. We will use the "TIME METHOD" to estimate percentages of loss due to air leaks in your plant.
1.Turn OFF all air operated end-user equipment.
2.Start your air compressor and let it cycle 5 times.
3.Time the OFF-LINE/UNLOAD TIME (not pumping time) using your watch. (Example: 5 minutes)
4.Time the ON-LINE/LOAD TIME (pumping time) using your watch. (Example: 2 minutes)
5.Calculate total percentage of air leaks as follows: Add the OFF / UNLOAD and the ON / LOAD times together: Example: T(5 minutes) + T (2 minutes)= 7 minutes) Divide ON / LOAD time T (2 minutes) by the total minutes: 2 ÷ 7 = 0.29
The result tells you 29% of your air compressors CFMs are doing nothing but maintaining your AIR LEAKS.
How to figure the cost of air leaks:
Based on values from the Compressed Air & Gas Handbook, we can assume
4* CFM per air compressor horsepower. So, if you have a 100 HP compressor and the above determined 29% air leaks -use this formula:
100 HP x 4*=400 CFM x 29% (.29 air leak loss) = 116 wasted CFM.
As the chart below shows, you now know that you are losing over ,000 a year because of AIR LEAKS.
SIZE OF YOUR LEAK CFM AIR LOSS WASTED DOLLARS PER YEAR
Orifice -----Diameter------Inches
1/32 -----------1.6 ----------211.70
3/32 ----------14.5 ---------1905.30
1/4 -----------104.0 ------13665.60
1/2 -----------415.0 -------54531.00
These figures are based on values from the Compressed Air & Gas Institute Handbook. Calculations assume a conservative cost of $.25 /1000 cubic feet of compressed air, 100% coefficient of flow and working 8,760 hours/year at 100 psig.
