Wireless connection blower to condenser? HELP

[HVACDoo]

Good afternoon everyone,

I have an 3 1/2 ton blower unit in my attic (space pac system) installed in my house. Recently the system blower would turn on, but the condenser outside WOULD NOT come on. After further diagnositcs with our HVAC team, they determined that there must be a break in the wire from the attic to the outside condenser (i.e. no power triggering the contactor) (tested with multimeter).

My question - IS THERE A WIRELESS OPTION?

To replace the 18/2 wire from the attic outside would require signficant efforts as it appears this was done at the same time as a major house renovation, so the wire was run under the floor boards, and tied to the coolant piping. I will have to run the wire around the entire house to repair.

Hoping a PRO could let me know if any such part exists!

Yikes, with 4!

I came across this link hvac-talk.com/vbb/showthread.php?71769-Broken-control-wire-can-t-replace&p=21016021#post21016021

any thoughts if this solution would work?

couldn't open your link, but you could install a wireless relay. They aren't cheap, but can be used instead of pulling in new wire

Our HVAC team that's rich.

Any good HVAC team should know how to make it a pump down system.

There is a wireless relay made just for that purpose. Not sold to the public but a dealer can get it.

Thanks everyone. I did call two HVAC people, one couldn't find out the problem, the tech with the multimeter found the bad wire.

I'll look into this solution, I appreciate everyone's help.

I found this company!

Thanks for pointing me in the right direction, if anyone knows any other products, happy to hear about them.

It might be cheaper to trace back and see where the broken wire is. A lot of times when I run into this it's in the control box outside - usually mice chewing the wires or a careless landscaper weed-whacking the wires.

Thanks, I'll try that. I inspected the wires around the unit, looked OK.

There were electrical contractors who were fishing new wire to replace knob and tube in the house, I fear they might have damaged internally somehow.

If lucky, only one of two of the conductors,is open. In that case, the tech can ground one side of the transformer and complete the circuit through the metal. As stated, wireless pump down works too, but may be cheaper to rerun wire.
Admittedly, an electrician may be more talented at fishing wires through walls.

I use a fluke tracer and can pretty well tell where the break is in the wall wiring, It has a significant range.
