fabmg Posted November 19, 2021 Share Posted November 19, 2021 Hello. Thanks for including me in the forum I have a Truma E2400 2017 which is working fine with the big flame (full capacity) but it gets on block (red light fixed) when I put it on small flame (half capacity). Does anyone had the same problem? Thanks in advance. Link to comment Share on other sites More sharing options...
Derek Uzzell Posted November 21, 2021 Share Posted November 21, 2021 Welcome to the Out&AboutLive forums. As I’m sure you are aware the Trumatic E2400 air-heater was discontinued some years ago, though some spare parts for it are still available. https://www.leisureshopdirect.com/gas/caravan-gas-fires/truma-fires/trumatic-e2400-lp-gas-heater-spare-parts Online comments relating to the E2400 usually involve it not working at all, but your heater evidently works OK on ’full heat’ but goes into failure-mode when you select a reduced output. Truma’s operating instructions for the E2400 include troubleshooting guidance https://www.manualslib.com/manual/1076469/Truma-Trumatic-E-2400-E.html?page=18 but don’t cover the specific problem you’ve described. Neither (as far as I can see) does that problem appear in the online complaints https://tinyurl.com/56e3xwav I’m not familiar with the E2400’s workings, so I don’t know how its output is ‘throttled’ technically. If you haven’t already done so, I suggest you contact the technicians at Truma(UK) to see if they can advise https://www.truma.com/uk/en/service/customer-service Link to comment Share on other sites More sharing options...
thebishbus Posted November 21, 2021 Share Posted November 21, 2021 I wonder if it could be restricted air flow . Worth checking for blockages to the air recirculate input and heater outputs, also the exhaust flue / air input hose. Brian B. Link to comment Share on other sites More sharing options...
Bra1n Posted September 22, 2022 Share Posted September 22, 2022 I have exactly the same problem recently, will check for restrictions to the airflow and report back Link to comment Share on other sites More sharing options...
Bra1n Posted September 22, 2022 Share Posted September 22, 2022 Feedback as promised and the good new is mine's working again. A lantern I had stored under the seat had moved close to the air inlet to the heater and was restricting the airflow, removed it and the heater now works on Low as well as High. :-) Link to comment Share on other sites More sharing options...
