hvac system not turning on...

[audi]

i have a restaurant and just noticed yesterday that when i go to turn on the heating system, nothing happens.

i tried the air conditioner and it doesn't work as well. i turn on the switch for the fan to come on manually and it too doesn't run.

does anyone have any ideas on what the problem is? i'd like attempt to fix it before shelling out $$$ for someone to come over.

if it makes a difference, we have had a good amount of rain this whole week.

thanks.

Check your system breaker. If that is OK call a Pro.

[blueline]

Could you please post a list of ingredients and step-by-step instructions for preparing the best dish in your restaurant. We would all like to try it before shelling out $$$ to eat there. After that maybe someone will be willing to help you.

People pay good money for good food. Bad food can kill people .Do you go to your mechanic to get your eyes tested ? Do you go to your optometrist to get your oil changed? An inexperienced person playing with high voltage can result in more than just items on the menu being blackened. Check your main breaker , then call a pro!!!!!

This question is something Like

I need a special meal for tonight but,
When I cook a meal it comes out wrong and taste bad, I do not want to go out and have to shell out $$$$ to a restaurant. Can you tell me what I am doing wrong?

As others have said check your breaker, if it is on call a pro. If you have to reset it do it only once. If you have to reset again don't.

don't go sticking your hands in something that could have 460 volts in it.
the result will not be a pretty sight.

I have to second that, Audi. One reset and call a local professional who can determine what's wrong and be alive at the end of the day to sit down with his family.

It would take most of us a long time to train to open a restaurant. There the legal requiremnets for food handling, the recipies, the sourcing for the ingredients, the advertising, the waitstaff...wow. Running a restaurant that meets the accounting standard of a "going concern" is difficult.

It's the same for what we do. While the internet is a great place to save all kinds of money, we can't take you by the hand and help you become an hvac detective if you hare not at home around 3-phase 460 power, and from what you described, you very likely have something wrong that is interupting your power supply.

So, with all due respect for both your ability as a businessman and your personal safety, get a referral from your chamber of commerce friends or someone you trust, and call that professional service person in to look at your system to safely find out what is wrong. That way, you will be happy and alive to spend many more years with your family AND your customers!

i want to apologize. i did not know this site was a forum of working professionals in the field.

i thought it was like all the other online open forums where the members are willing to share their experiences. much like brighthand.com, audiworld.com, audizine.com, mbworld.org.

so again, i want to apologize and i was not trying to insult anyone.

:) Audi,
Check the power sounds like it may have been shut off if you are just turning it on for the first time this season. Problem is only you can see what you have and we would just be guessing. This would require a lot more information. Just saying it will not turn on would be to start with the power.
Good luck,

i just went up with a friend. the fuse box panel i have has 3 cylinder fuses. labelled "fusetron frn r45"

i noticed that all the wires were fine except for the left one. there was one wire that was sticking out.

friend is going to try and replace the fuse for me. so hope that works.

Dear Audi,

First and foremost, welcome to our forum. This is a forum, as you pointed out, of professionals that share their common knowledge, training, problems, stories, and yes, their work experiences.

So your friend and you have found a “wire sticking out” of the service disconnect on the roof. You’re going to have your friend replace the “time delay 45 amp” fuse and then turn the disconnect back on, and hope the unit starts,…..is that about right?

I have some questions for you and your friend, they are as follows:

Why are you replacing the fuse to begin with, did you friend find it blown?

What about the wire that is sticking out of the service disconnect, are you going to leave it alone, or are you going to reconnect it, and if so, where?

When you turn the service disconnect back on, is your friend going to have an amprobe monitoring the incoming power? (after 33 years in the trade, I wouldn’t restart the system without one under the circumstances you have posted).

And if the system doesn’t start, what is your next move?

And if it does start, what is your next move? Are you just going to leave it alone, remember the fuse blew( this is a primary safety device to protect your conductors [wires] from melting).

Friend…..and I call you friend, we here at this forum have no vested interest in wither you call a qualified contractor or not, but we do have a moral, and ethical reason to HIGHLY RECOMMEND that you call a qualified contractor to deal with your problem, and this is based on not only the countless years of field experience we poses, but more importantly is based on the potential horrors, and dangers that we all know wait you should you go further in your endeavor.

I have 33 years of field experience, thousands of hours of industry training, several certifications, have taught school and seminars, thousands of dollars worth of test and safety equipment, and I have to watch out every day that I don’t make a mistake and not make it home to my wife and six children.

Friend……….don’t be stupid, it’s not worth it.

Most Respectfully Submitted,
John J. Dalton CM

Well said, John, and nice to see you around these parts again.

I just saw the "CM" by your signature....I didn't know you were a CM. I'm hopin' to join you in that rank...possibly this year when I can get time to sit for a test.

To the OP...please get a qualified pro out to your business. Would you want an interior decorator working on your convection oven or walk-in cooler (no offense to interior decorators...just wantin' to make a point)?

I can see the News headlines now "Owner and friend Bar-b-qued at Rib joint".:D

[chenz68]

Im a professional that's been in the trade for only 2 years and Im very impressed with all the comments made to the Rest. owner regarding his problem. It seems obviously that it can be very dangerous if some one inadvertantly give him info on how to check the unit....I'm proud to be in this industry,,, Good Job Pro's

[timebuilder]

I like John Dalton's comments. It's unnerving to imagine Audi and his friend trying to decide what to do with the "wire sticking out," or deciding how to replace the fuse in what is very likely in a 460v, 3-phase disconnect enclosure.

Audi, I may not earn even a penny from your use of a professional for this problem, but I will feel very good if the job is properly handled by an experienced man using established standards of safety while performing workmanlike service.

Audi, while we all like free sources of information on the net, sometimes that information is best imparted in a classroom or apprentice environment. It's taken me literally 45 years to learn what I know about electricity, electronics, and mechanical systems, from kit radios and automobiles to control systems and jets. I'd have to be there to guide you in a step by step, tool by tool manner, so I could ensure your safety and the effectiveness of the repairs.

i paid someone to fix my transmission cause i didnt know how and i wasnt going to fork out the $$$ and time to learn.
