Returning To Replace ANOTHER Bosch Board! 

I actually figured that out after doing a few of these. Lol. Never bothered to read the directions 🤦

Good call

Both repairs have been covered under warranty. They were down for a week.

The new inverter driven, fancy stuff works very well, and often very reliably... If designed correctly. This particular unit likely has some sort of a design fault, judging by the fact that the replacement board had a different brand, and size of capacitors attached to the component that failed. Think about how long your VCR, or stereo from the 80's has been working. There is really no reason why these things can't last decades, but on occasion, manufacturers make mistakes.

@@JeffsHVACAdventures definitely parts warranty, but did they have to pay for labor?

Yea this is the second one for this unit

The Bosch makes IDS 15, 18, and 20 series, those numbers do not equate to automatic seer ratings, those are up to ratings. There are many combinations and Both HSPF and SEER vary with them, my company have about 40 Bosch systems under our belt starting in 2019, majority have been the IDS 18, a few IDS 20, and several IDS 15. Also have not had a single failure with any of them. All are a mix of new construction and replacements. If you look at ARI ratings, there is a huge difference like all manufactures between HP with air handler and Duel fuel SEER performance, we do more duel fuel and the IDS18 and 15 make more sense. Even in a strait HP/AH situation the 20 only hits that SEER in a certain situations. But then in replacements, we evaluate and test the most critical component and base equipment of of that. Which is the duct system. If I cannot correct a poorly designed and sized duct system, my customer gains nothing by purchasing higher SEER. This isn't a concern in new construction for us, as all systems are Designed using manual J, D, and S criteria. Bottom line is SEER and HSPF vary hugely by capacity and unit series, but neither number are as important as having a duct system that lets them achieve that number. In my 36 years I cannot count the time I dealt with unhappy customers that bought High efficiency that didn't meet claims, when lower efficiency with a proper duct system would have. I forget if it was proctor engineering or the Energy conservatory, or another that did a great est on that theory in the 90's, but results were that a properly sized, designed and installed lower rated system, beat out the highest efficiency rated units when not properly sized, designed and installed. Numbers matter, but some matter more than others, and SEER isn't the one that matters most.

407c is being phased down just like 410a, but I agree that as these systems get more complicated failure becomes more likely.

@@Ali.A72 407 c I read was not bieng phased out yet. But 410 a is. Also 407 c contains r 134 a as part of the blend but personally I am liking that r32 is coming on the market which for the first time since r22 is a pure refrigerent and not a blend despite it's having a slightly flammable classification. Question is will it work to convert over a 410 a system or are we going to have to resort to buying Walmart duster cans or endust duster cans to charge up a 410 a system. Which is meant for electronics. Point is this country needs to stop with 50 different types of refrigerent that can be used the automotive industry did not do that after the switch from r 12 to r134 a it should have never been done with residential or Comercial hvac either. And that is also part of the problem along with all these American companies sticking to old methods and designs and then trying to dump an inverter type system on it and then throw proprietary comunicating systems in the mix. You don't need that for efficiency. Or switch to 2 split systems and rip out the ductwork on a 2 zone system like I saw one hvac youtuber do. And fine replace the old package unit 5 ton. From like 1984. But don't rip out all the ductwork And make 2 ducting systems And install 2 gree flex 3 ton units. When all they needed to do was install and hookup a gree flex 5 ton split system and leave the ductwork in place with the dampers for having 2 zones. Meaning a thermostat for the upstairs in addition to the downstairs and the damper or whatever it is called The inverter technology alone is going to reduce their electric bill. And do a better job cooling the upstairs fine if you need to redo all the ductwork but don't make it more complicated then it needs to be. Especially with heat pumps. It's called concerning the ductwork if ain't broke don't fix it. Just so you can Reem extra money from Someone by selling them 2 3 gree flex units . Plus the cost of redoing all the ductwork and not doing how I like it. When all you needed to do was just sell them one 5 ton gree flex which is 1 thousand more VS the 3 ton. It's a little over 4 grand. And that's another problem that contributes to all these system issues.

bosch units are made by Midea, which is a chinese company. i dont know if midea reached out to bosch to use their name (kickbacks), or vice versa. that's why i would only go for the M18M models, with mitsubishi compressors and not midea's. Midea and Cree are both chinese companies, along with many others, they're 2 of the top manuf for ductless systems/side discharge branded under Carrier or toshiba.

Right you are friend! 🤙

What's the warranty on the board...thanks

@@VooDooV610 years

These boards aren’t hard to get. 3 days.

That’s good! I’ve heard people complain it was a month or more for the condenser fan motor

It acts as an insulator to keep the heat from the heat sink away from the board.

This is the first one that actually burnt a hole. The other two were recommended by Bosch tech support to be replaced due to phantom errors. Bosch never actually gave me a solid reason. Everything checked out and voltage is good coming in.

It is not uncommon for a Bosch Heat Pump to have long run times at low speeds. I’d say if you’re still concerned after a week to 10 days of installation, call the installation company back and let them know your concerns.

@@JeffsHVACAdventures 8-10 hours seems uncommon to me, do you have any advice for me so I can address it with the installer

@@adekunleogunwumiju4905 A couple things I would check for is to make sure the home is well insulated. Make sure the windows and doors make good seals. A well insulated house can make a huge difference in HVAC performance. Also make sure the thermostat location makes sense for the way the house and HVAC system is laid out. It could be an issue with the system but I would have those things checked.

Yea I figured that out after doing a coupe. Lol thanks 🤙

This is the 2.0.

The way Mikey talks that them boards are in the thousands to replace

What companies have learned (and this applies to about everything) is that the more complex they make things the more likely consumers will just upgrade with new. It works to their benefit not to produce simplicity. Government assists by requiring the efficiency of the complex equipment.

@@JeffsHVACAdventures Yes, but only the 15s. Haven't had a single issue on the 18 and 20s.

This one is around $900 for the 15Seer. But no, When I was on the phone with Tech Support they never gave me an answer. Just sent me a board.

I don’t remember what the original code was when I replaced it the first time, but this time it didn’t throw a code. It just wouldn’t come on.

The board is $900. But everyone I’ve done has been covered under warranty

Yea it’s 100% a Bosch thing. It’s a known problem that they are just warranting with little to no troubleshooting

Maybe they repair them at the factory. All the Bosch boards I’ve done have been warranty.

Thanks but I was referring to the typo on a $900 board's manual. Same guy might be with the QC dept.@@JeffsHVACAdventures

Thanks

Thanks for watching!

So each year year my company installs an average of around 100 systems between new construction and replacements. We deal American standard, Comfort Maker, Haier, Mitsubishi, and Bosch. American standard and Comfort Maker are American companies, with split manufacturing in the USA and Mexico. Mitsubishi is a Japanese company with Japanese manufacturing, but they have partnered with Trane/American standard. Haier and Bosch are both German companies that have partnered with China on manufacturing, Haier is also a G.E. partner. So for every failure/callback on Mitsubishi, Haier, or Bosch we have around 10 on American standard and Comfort Maker, Comfort maker by the way is mostly of Carrier designs and technology and ICP the parent company is the largest in the world. So believe what you want, but as a 36 year veteran of HVAC, I see it vice versa. America sold of and out sourced it's manufacturing, and while we focus on Diversity, Inclusion, and Equality, the Asians focus on well not doing what we did.

You have to ground the unit
