420G Puritan Bennet

[CPAPARTY]

Recently my 420G stopped working ,I tried to find a service company but could not find one. I researched the problem . I went to Craigs list and goy a 418g FOR 50.00
IT WORKS GREAT but it is the size of small shoe box. I want the compact 420G . I took it apart tested the board and could not find a glass fuse like the 418G has. I found out that it has 420G a fuse 3amp soldered on the board I went to Mar Vac a local electronic supply and got a 3 amp pico fuse and soldered onto the board. I now have power.
I got a E 7 error and this forum says it is a blower motor . The blower does not freely spin. I guess I will find a replacement somewhere. I will report how that goes.
Sunday I take another sleep study so my Med plan can give me a new one CPAP that is. I still would like to fix the 420G.

You might check this auction link from time to time. I believe there were some listed on it recently.
Otherwise there are some listed that are probably better than the 420G. They seemed to have a history of blower problems.
